Recently, the market supervision departments in many places issued a notice on the unqualified food sampling list. The Paper combed and found that it involved many problems such as pesticide residues and microbial pollution. The market supervision department has carried out verification and disposal work.

　　It is noteworthy that coliforms were detected in tableware and rice noodles in the unqualified sampling list of several batches of food published by Tai ‘an Municipal Market Supervision Administration and Baise Municipal Market Supervision Administration.

　　Why are coliforms detected in tableware and rice noodles? Kai Zhong, deputy director of Kexin Food and Nutrition Information Exchange Center, said that coliforms mainly come from the intestines of warm-blooded animals, but they are widely distributed in nature. Dishes, rice noodles and so on have coliforms exceeding the standard, mostly because of secondary pollution.

　　Many enterprises were found to contain coliforms in their products.

　　On July 5th, Tai ‘an Municipal Market Supervision Administration issued the information circular on food safety sampling inspection (hereinafter referred to as the circular), which disclosed problems such as excessive pesticide residues and microbial pollution.

　　According to the notice, coliforms were detected in the tableware plates of Fuchunyuan Restaurant in Taishan District and Shandong Xiaolongxiao Jiutian Catering Management Co., Ltd. in Taishan District. According to the national food safety standards, coliforms should not be detected in tableware.

　　Tai ‘an Municipal Market Supervision Administration said in the notice that the market supervision department of the place where the production and operation enterprises are located has ordered the enterprises to find out the product flow, recall and remove the unqualified products, control risks, file an investigation, and analyze the reasons for rectification. The unqualified products involved have been verified and disposed of as required.

　　The Paper combed and found that Baise Municipal Market Supervision Administration had previously released the 26th food safety supervision and sampling information announcement in 2021 on July 1, which also showed that the prepared fresh and wet rice noodles sold by Guangxi Tiandong Weimeijia Agricultural Products Development Co., Ltd. and tianlin county Huaxu Food Co., Ltd. were all found to have coliforms.

　　Kai Zhong, deputy director of Kexin Food and Nutrition Information Exchange Center, said that coliforms are the general name of many bacteria, including Escherichia coli. It is a hygienic indicator bacterium, but it does not lead to disease if it is detected. The higher the detection value, the greater the possibility. Coliform bacteria can be detected in many foods, but as long as there are no pathogenic bacteria, it will generally not cause health hazards. As for the source of coliform bacteria, Kai Zhong said that coliform bacteria mainly come from the intestines of warm-blooded animals, but they are widely distributed in nature. Dishes, rice noodles and so on have coliform bacteria exceeding the standard, mostly because of secondary pollution.

　　According to the interpretation information released by the market supervision department, coliform bacteria is one of the commonly used indicator bacteria for food pollution at home and abroad. The detection of coliform bacteria in food suggests that it is more likely to be contaminated by pathogenic bacteria (such as Salmonella, Shigella and pathogenic Escherichia coli). Excessive coliform bacteria may be caused by the pollution of processing raw materials and packaging materials of products, or the pollution of products by production equipment and environment such as personnel and tools during production, and the incomplete sterilization of products with sterilization technology.

　　A variety of foods were found to have excessive drug residues.

　　In addition to coliform bacteria, some enterprises have been found to have drug residues and other problems. In the notice issued by Tai ‘an Municipal Market Supervision Administration on July 5, the bureau disclosed that the content of "procymidone" in leeks sold by Baxianju Commercial Bank in Ningyang County and Yanzhuang Haiwei Supermarket in Daiyue District was higher than the national food safety standard.

　　The Paper combed and found that in recent food sampling notices issued by many market supervision administrations, the problem of unqualified drug residue detection of enterprise-related products appeared.

　　On July 2nd, the 7th notice of Gansu Provincial Market Supervision Bureau on the sampling inspection of unqualified food showed that chloramphenicol, a drug banned from food animals, appeared in Jinghui brand acacia honey produced by Gansu Jinghui Bee Industry Co., Ltd..

　　On July 5, 2021, Jilin Provincial Market Supervision and Management Department’s 27th notice on unqualified food showed that the carp sold by Fengyun Aquatic Products Company in Automobile Industry Development Zone, Wuchang Fish sold by Yixin Aquatic Products Store in Chaoyang District and snakehead sold by Guo Di Seafood Wholesale Company in Kuancheng Agricultural Products and Aquatic Products Market were all found to exceed the standard.

　　The attachments of the above-mentioned relevant notices show that excessive coliforms are likely to cause intestinal diseases such as dysentery, which may cause symptoms such as vomiting and diarrhea. The pesticide procymidone is irritating to people’s eyes and skin. Long-term consumption of leeks with excessive procymidone residues may cause neurological disorders.

　　The market supervision department reminds consumers that when they find the unqualified products involved in the notice, they can call the 12315 hotline to complain or report.

The cold wave strikes, and every time this season, colds seem to become "frequent visitors." In the office, subway and bus … I hear sneezing and coughing from time to time.

Many people have complained that they feel weak all day after catching a cold, and their whole body aches, and sometimes they have fever, which is even heavier than usual colds. If you have the above symptoms, you are likely to have influenza, also known as flu.

Winter is the season of influenza, and the intensity of influenza is increasing in many places at present. How can we prevent it? How to distinguish influenza from common cold?

Today, we invited Li Yanhong, director of Peking University Shenzhen Hospital, to lead us to understand the flu and take preventive measures during the winter solstice.

National monitoring data show that influenza is the main respiratory infectious disease in China, and the number of reported cases in China is increasing gradually, among which influenza A virus and influenza B virus are the main sources of infection.

The flu is coming, which makes people wonder why it is more vulnerable to the flu in winter.

First of all, when the temperature drops in winter, the influenza virus is more likely to survive and spread in a cold and dry environment.

The transmission route of influenza is mainly respiratory droplets, and it can also be transmitted directly or indirectly through oral cavity and nasal mucosa. In winter, people prefer to move indoors, with many people in contact and a relatively sealed environment, which undoubtedly creates good conditions for the spread of the virus.

Secondly, the immune system may be weakened in a cold environment, and in winter, people do relatively little exercise and outdoor activities, and the sunshine time is short, which leads to the decline of vitamin D level, relatively weak immunity, and are more susceptible to influenza virus infection.

Furthermore, if you still have bad habits such as unbalanced diet and lack of adequate sleep, which affect the health of the immune system, the flu will easily find you.

In a word, the increase of influenza patients in winter is the result of many factors, from environmental conditions to people’s behavior habits, which will affect the spread and incidence of influenza.

Influenza and common cold are two different respiratory diseases. Although they are both caused by viruses, there are some differences.

● Virus type: Influenza is caused by influenza virus, while common cold is caused by many different viruses, such as rhinovirus and coronavirus.

● Severity: Compared with a cold, the course of influenza is generally longer, taking 5-10 days, and the symptoms are usually more serious, mainly including high fever, severe headache, body aches, cough and sore throat. The common cold can be cured in 5~7 days, and its symptoms are relatively mild, usually manifested as respiratory symptoms such as stuffy nose, runny nose, cough and sore throat.

● Onset speed: The onset speed of influenza is relatively fast, and the illness is rapidly aggravated within one or two days. The onset of the common cold is slow, and the symptoms gradually appear.

Comparison of onset speed

● Scope of infection: Influenza usually causes a large-scale epidemic, while the common cold is commonly spread among individuals.

● Risk of complications: Influenza may cause serious complications, such as pneumonia, myocarditis and craniocerebral encephalitis. The common cold generally has fewer complications.

Generally speaking, the flu is relatively serious and spreads quickly, while the common cold is lighter and has a smaller spread range. In terms of treatment and prevention, influenza needs more attention, while the common cold can generally be relieved by rest and appropriate drugs.

At present, influenza has entered a period of high incidence, and the following susceptible groups need special attention.

For example, pregnant women, young children, the elderly, patients with chronic diseases such as heart disease, lung disease and diabetes have relatively weak immunity and are more susceptible to influenza virus.

Although influenza is mostly a self-limited disease, symptomatic treatment is generally adopted to alleviate symptoms, but a few patients can develop pneumonia and even rapidly develop into severe diseases.

Therefore, for people susceptible to influenza, it is necessary to do personal protection.

The key to prevent influenza is to strengthen personal protection;

◆ Pay attention to hygiene: wash your hands with soap and water frequently, or use alcohol-based hand sanitizer, especially after touching public places, coughing and sneezing.

◆ Healthy lifestyle: keep enough sleep, eat a balanced diet, exercise moderately, improve your immunity, and keep windows open and ventilated every day at home.

◆ Wear a mask to avoid contact with viruses: Be sure to wear a mask when going out, try to avoid close contact with people who have been infected with the flu, avoid going to crowded places, and reduce the chance of infection.

◆ Vaccination against influenza: Influenza vaccine is one of the most effective ways to prevent influenza. Regular vaccination against influenza can improve immunity and reduce the risk of influenza infection. In particular, people with poor resistance can be vaccinated against influenza in advance.

If you have flu symptoms, it is recommended to rest at home and keep enough rest. Minimize contact with others, drink plenty of water, and properly ingest foods rich in vitamin C, such as citrus fruits and green leafy vegetables, which will help relieve symptoms. For ordinary patients, it is mainly symptomatic treatment.

○ fever < 38.5℃: physical cooling.

○ High fever (≥38.5℃): antipyretic drugs such as ibuprofen and acetaminophen can be taken;

○ Cough and expectoration: ambroxol hydrochloride, acetylcysteine, Su Huang to relieve cough;

○ Diarrhea: probiotics, montmorillonite powder, etc.

At the same time, it is also necessary to use targeted anti-influenza drugs, such as oseltamivir and mabaloxavir. However, it should be noted that oseltamivir and mabaloxavir are mainly used for the treatment of influenza A and B, but not for the common cold and bacterial infection. And when used for treatment, the sooner the flu symptoms appear, the better, and it needs to be taken within 48 hours after the symptoms appear, which can shorten the duration of symptoms.

Tips: oseltamivir and mabaloxavir are prescription drugs, so it is best to take them under the guidance of a doctor.

We will develop auto financing leasing in an orderly manner, encourage auto manufacturers, sales enterprises and financing leasing enterprises to strengthen cooperation and increase the supply of financial services.

All regions and relevant departments should earnestly strengthen organization and leadership, refine work measures according to their responsibilities, promote relevant policies and measures to take effect as soon as possible, and further promote the recovery of automobile consumption and the release of potential.

　　As the greatest industrial product in the 20th century, automobiles have greatly changed people’s lives, expanded their travel radius, brought great convenience to people and improved their quality of life. Everything is a double-edged sword, and life on wheels has both advantages and disadvantages.

　　However, with the growing demand for short-distance travel, a considerable number of domestic manufacturers are aiming at the blue ocean market of "Old Man Le", creating the dream of owning a luxury car with a price close to the people, avant-garde fashion and tens of thousands of yuan. A considerable number of "three noes" products were born, but the following problems are great traffic safety and personal safety hazards, driving on the road without a license and without a license, causing countless painful accidents. Here, Sina Auto appeals to consumers to buy cars legally and reasonably, not to buy low-speed old scooters easily, and not to go on the road illegally.

　　Is there really no other choice except the low-speed old scooter within 100,000 yuan? Of course not. Today’s article will recommend several pure electric vehicles that are affordable, small and lovely, can meet national laws, regulations and related policies, and can legally drive on the road.

　　Wuling Hongguang MINIEV

　　Official guide price: 28,800-46,800 yuan.

　　It is true that Wuling will build whatever the people need! Wuling Hongguang MINIEV achieved sales of more than 420,000 vehicles from January to December in 2021, which shows how accurate Wuling is in controlling consumer demand. After all, only when the buyer’s market is strong enough can the seller’s excellent data be achieved.

　　It seems no exaggeration to regard Wuling Hongguang MINIEV as a national electric vehicle. As a mini-car, Hongguang MINIEV adopts the layout of front and rear drive and three doors and four seats. The permanent magnet synchronous motor it carries can provide the maximum torque of 85Nm and the maximum power of 20kW. The NEDC mileage of the model equipped with ternary lithium battery is 120km, and the cruising range of the model equipped with lithium iron phosphate battery is 170km. At the same price, it is wise to buy a national car that can legally go on the road.

　　BYD Dolphin

　　Official guide price: 96,800-12,480 yuan

　　BYD Dolphin occupies many firsts of BYD brand, such as: the first model adopting BYD’s brand-new Logo, the first marine car model, the first model based on E platform 3.0 and so on. The appearance design of BYD Dolphin is eye-catching, and the bionic design all over the car is easy to get the favor of soft and cute girls.

　　BYD Dolphin has certain advantages in size. It is a typical small car, and its actual interior space is more advantageous than other fuel vehicles of the same level. If you travel daily, the model equipped with 70kW motor can meet the requirements. If you have higher requirements for the performance of the vehicle, you can choose the Dolphin Knight Edition equipped with 130kW motor. Entry-level models can achieve a NEDC mileage of 301km, and models equipped with larger battery packs have a NEDC mileage of over 400km. The rotating screen on the center console is enough to prove the inner strength of BYD Dolphin. Is such a car attractive enough?

　　Ou la hei Mao

　　Official guide price: 69,800-84,800 yuan.

　　In the past two years, the word "slap cat" has appeared more and more frequently. Almost everyone has a few friends who are keen on slapping cats in their circle of friends. If you drive a car with the word "cat" in its name, will it be as happy as slapping cats? The brand of Euler has prepared such a black cat for consumers that can make you sigh.

　　Euler Black Cat has a retro appearance. As an entry-level model of Euler brand, Black Cat is equipped with two kinds of motors with 35kW and 40kW power, and adopts the layout of front drive and four doors and five seats. The cruising range of the entry-level model NEDC is 301km, the cruising range of the main model NEDC is 351km, and the cruising range of the top model NEDC is 401km. In the fast charging mode, it can be charged to 80% in half an hour, which is very cost-effective.

　　Chery new energy xiaomayi

　　Official guide price: 66,900-82,900 yuan.

　　Little Ant is an entry-level model of Chery New Energy, and it has captured a large number of young consumers from the listing place, including many young ladies with extremely high values. With its lovely appearance and cruising range of more than 300km, it has gained a considerable number of orders.

　　It is easy to get confused about the names of the micro-sugar version, the semi-sugar version and the full-sugar version when I look at the configuration table for the first time. In fact, different sugars represent different configurations. The sweeter the configuration, the higher the configuration. All the models are equipped with ternary lithium batteries or lithium iron phosphate batteries in different configurations. Which one to choose depends entirely on personal preferences. In addition, the small ants adopt the layout of rear drive, which can provide driving pleasure. Only after they have tried it can they know whether it is as sweet as a cup of milk tea.

　　Nezha v

　　Official guide price: 62,900-12,080 yuan.

　　Nezha V is a rare small SUV pure electric vehicle in this class. After seeing enough mini or small hatchback, is this cute small pure electric SUV more appetizing?

　　Nezha V is equipped with a 40kW or 55kW permanent magnet synchronous motor. The NEDC cruising range can be 301km for the standard cruising model and 401km for the long cruising model. The layout of the front driver has made great contribution to the trunk volume of Nezha V. In the fast charging mode, it only takes half an hour to charge to 80%.

　　Zero run T03

　　Official guide price: 68,900-84,900 yuan.

　　Compared with other models, the zero-run T03 may have a lower brand awareness, but it is the fastest charging model in the slow charging mode among all the models recommended today. It takes only 2.75 hours for the entry-level model and 3.5 hours for other models to charge to 100%.

　　The design of the zero-run T03 is very classy, and it is easy to be recognized as an imported or joint-venture brand. It is worth noting that only the entry-level model of zero-run T03 is equipped with 55kW motor, and the cruising range of NEDC is 301km, while other models are equipped with 80kW motor, and the cruising range of NEDC reaches 401Km, which is not common in this level.

　　Baojun KiWi EV

　　Official guide price: 69,800-89,800 yuan.

　　Baojun KiWi EV is the most futuristic model among all the recommended models today. The two grooves on the bumper are very suitable for sitting in the front of the car to get a group of photos that are highly praised in the circle of friends. The rich body color matching is in line with the pursuit of personalized body color by young consumers.

　　Baojun KiWi EV is equipped with a 40kW permanent magnet synchronous motor, with a cruising range of NEDC of 305km, which can be charged to 80% in one hour in fast charging mode and 100% in slow charging mode. The battery life and charging efficiency are not excellent, but in the face of Baojun KiWi EV’s sci-fi modeling, it is quite necessary to forget the cost performance for a short time.

　　Redding mango

　　Official guide price: 29,800-56,900 yuan.

　　Everyone may have some models of the Reading brand, but Bidewen behind the Reading brand is famous, especially in the sales of electric bicycles. After finding the new target, the mango model launched by Reading Electric Vehicle, with a starting price of 29,800 yuan, has become the most direct competitor of the elderly scooter that cannot legally go on the road together with Wuling Hongguang MINIEV.

　　As Reading, who has little experience in building cars, Mango models are equipped with 25kW and 35kW motors, and only the top models equipped with 35kW motors support fast charging mode. Other models can only be charged through slow charging mode, and the charging rate is 100% in 8 hours. The cruising range of NEDC is 130km, 200km and 335km for top models with different battery capacity. Although the data is not excellent, the biggest advantage of reading mango is that the starting price is close to the people.

Notice of the General Office of the Ministry of Commerce on Promoting the Brand Chain Development of Convenience Stores
Commercial circulation letter [2019] No.223

The competent commercial departments of all provinces, autonomous regions, municipalities directly under the Central Government, cities under separate state planning and Xinjiang Construction Corps:

In order to implement the spirit of the Central Economic Work Conference and the deployment of the Government Work Report, adapt to the trend of consumption upgrading, improve the convenience of commercial facilities, improve the convenience of consumption and the quality of life of residents, adhere to the people-centered principle, and meet the people’s growing needs for a better life, the Ministry of Commerce decided to promote the construction of brand chain convenience stores throughout the country. The relevant matters are hereby notified as follows:

First, attach great importance to the development of brand chain convenience stores

Convenience store is the retail format closest to the lives of ordinary people, and it is an important carrier to meet people’s convenient consumption needs and serve people’s livelihood. In recent years, China’s brand chain convenience stores have accelerated their development, ranking in the forefront of retail formats for many years in a row. However, there are still problems such as insufficient total number of brand chain stores, unreasonable layout, imperfect service functions, and weak management ability. Promoting the development of convenience store brand chain is conducive to improving consumption convenience, improving consumption quality and stimulating consumption potential, which is an important livelihood project. All localities should raise awareness and put the development of brand chain convenience stores into an important work agenda, as an important starting point for implementing the consumption upgrading action plan and promoting the transformation and upgrading of physical retail, and continue to promote it in a planned and step-by-step manner.

Two, combined with the actual situation to determine the key to promote the city

The development of brand chain convenience stores is promoted by cities. According to the working steps of "overall deployment, key promotion and gradual extension", the development of brand chain convenience stores in municipalities directly under the central government, cities with separate plans and provincial capitals should be started first in 2019. On the basis of focusing on promoting these cities, all localities can choose some other cities to promote them in combination with the actual local economic development.

Three, pay close attention to the development of brand chain convenience stores.

Local competent commercial departments should guide the relevant cities to combine the existing work basis, promote branding, chaining and intelligence according to the spirit of the National Conference on the Development of Brand Chain Convenience Stores and the requirements of the Compilation Points of the Work Plan for the Development of Brand Chain Convenience Stores (see Annex), pay close attention to the study and formulation of work plans, and clarify work objectives, work priorities and safeguard measures. It is necessary to organize consulting institutions, think tank experts, industry associations and business representatives to participate in the formulation and demonstration of the plan, so as to improve the pertinence and operability of the plan. Municipalities directly under the central government, cities with separate plans and provincial capital cities should submit their work plans to the Ministry of Commerce before the end of July, and other cities should submit them before the end of September.

Fourth, improve the policy system to support the development of brand chain convenience stores

In view of the outstanding problems affecting the development of brand chain convenience stores, all localities should learn from the practices of Beijing, Xi ‘an, Fuzhou and other cities, focus on deepening the "streamline administration, delegate power, strengthen regulation and improve services" reform and optimizing the business environment, promote the introduction of policies to support the development of brand chain convenience stores, and provide support from the aspects of store location, registration, business license, technology application and supply chain construction, so as to create a good business environment for the development of convenience stores. We must do a good job in the implementation of the policies that have been introduced.

V. Strengthening organizational guarantee

The Ministry of Commerce will establish a three-level linkage working mechanism among departments, provinces and cities, study and formulate the development indicators of brand chain convenience stores from the aspects of convenience store layout, development quality, policy environment and working mechanism, and focus on guiding and promoting municipalities directly under the central government, cities with separate plans and provincial capitals, and make quarterly statistical summary and feedback on the progress and problems. The provincial commerce departments should strengthen the supervision and guidance of relevant cities, clarify the timetable and phased results, compact the work responsibilities, and put the work plan in place. Relevant cities should establish an inter-departmental coordination mechanism and give full play to the role of relevant functional departments and grassroots governments such as districts, counties and streets; Establish a normal communication mechanism between government and enterprises, and listen to and solve problems encountered in enterprise development in a timely manner.

Six, timely summary and promotion of typical experiences and practices.

Key points of compiling the development plan of brand chain convenience stores

All localities should scientifically plan the general idea of developing brand chain convenience stores on the basis of in-depth investigation and extensive consultation, combined with local consumption level, consumption characteristics and convenience business development, fully embody the principles of government guidance, market operation, focusing on people’s livelihood and diversified development, organize the preparation of a good work plan, and clarify development goals, main tasks and safeguard measures. The work plan shall be prepared by the competent department of city commerce and approved by the local people’s government. The work plan shall include but not limited to the following aspects:

First, the foundation of development

Focus on the basic situation of the city’s economic and social development, residents’ consumption and convenience business development, and find out the basic base of the main chain brand enterprises of convenience stores in this city. Basic data such as the number of existing brand enterprises, the number of stores, and the basic layout should be fully grasped (the data is as of the end of June 2019) as the baseline for evaluating the progress of the work, and clearly reflected in the work plan in the form of a list.

Brand chain convenience stores refer to convenience stores that operate directly or by joining, with unified image identification, unified store management and control, unified facilities configuration, unified service standards, unified commodity procurement and unified logistics distribution. Enterprises with unified trade names and logos and low standardization in other aspects are not included in the statistical scope of brand chain convenience stores.

Second, the development goals

The development goals are planned in three years, with the end of June 2019 as the benchmark, indicating the goals achieved in each year. Goals can be set in both quantity and quality. In terms of the number of development, it is necessary to make clear the two quantitative goals of brand enterprises and brand chain stores, and at the same time, set the structural development goals from the dimensions of community, distance or population around building a "quarter-hour convenient life service circle" in combination with local reality. It is necessary to highlight the organization and scale orientation, and focus on developing brand chain enterprises with more than 50 chain stores and high reputation and integrity. In terms of development quality, it should reflect the achievements of convenience stores in improving service functions, improving service capabilities and upgrading modernization level.

III. Main tasks

Clear the main tasks of developing brand chain convenience stores, and explain the measures taken in optimizing the layout of convenience stores, improving the convenience service level and strengthening the application of information technology.

Optimize the layout of convenience stores. This paper focuses on the measures to be taken in increasing the resources of convenience stores, expanding the network of brand chain convenience stores and cultivating leading enterprises. According to the situation of commercial facilities, consumption level and consumption habits in different regions, the allocation standards of convenience commercial facilities such as convenience stores should be studied and formulated. Increase the applicable store resources of convenience stores through multiple channels, promote the implementation of the requirement that the area of commercial and comprehensive service facilities in newly-built communities accounts for no less than 10% of the total construction area of the community, and strengthen the security of convenience stores. It is necessary to combine the renovation work of old urban communities, and use the space resources that have been withdrawn from rectification to encourage brand chain convenience stores to settle in. Promote hospitals, universities, stadiums, parks, scenic spots and other public service places to open store resources to brand chain convenience stores. Encourage brand chain convenience store enterprises to transform and upgrade old small shops, grocery stores, canteens and other decentralized convenience stores. Encourage the introduction of well-known brand chain convenience store enterprises with cross-regional development.

Improve the level of convenience services. This paper focuses on the measures to be taken to support convenience store enterprises to expand their business scope, improve service standards, strengthen logistics and distribution capabilities, and transform and improve service environment. It is necessary to support convenience store enterprises to develop their own brand products, expand the sales of fresh food products, provide on-site manufacturing and selling services such as simple meals and drinks, and carry various kinds of convenience life services. Encourage the extension of convenience store business hours and support the opening of 24-hour convenience stores. Support brand chain enterprises to build their own or adopt third-party logistics services, implement joint distribution and centralized distribution, and build an intensive and efficient logistics distribution system. Encourage qualified enterprises to develop food and fresh products production bases and central kitchens, and establish a whole cold chain distribution system. Guide enterprises to benchmark leading enterprises in the industry, establish high-level service standards, optimize processes and enhance service experience. Advocate the concept of green consumption.

Strengthen the application of information technology. This paper focuses on the measures to be taken to support the digital transformation of brand chain enterprises and promote the intelligent and intelligent development of chain operations. Encourage enterprises to integrate chain store resources and online traffic resources, and carry out online and offline integrated operations. Support chain enterprises to apply technologies such as cloud computing and artificial intelligence, and establish a smart supply chain driven by consumer big data, such as commodity procurement, inventory management and order management, to improve operational efficiency. We will promote payment technologies such as self-service settlement, code scanning payment, and face-brushing payment, and encourage the use of commodity management technologies such as digital shelves, electronic price tags, and wireless radio frequency, so as to improve the level of service intelligence and optimize the consumer experience.

Fourth, safeguard measures

　　62.4%　

　　Contribution rate of agricultural science and technology progress　

　　To build an agricultural power, the sharp weapon lies in science and technology. In recent years, China’s agricultural science and technology innovation ability has been steadily improved, and the contribution rate of agricultural science and technology progress has increased from 54.5% in 2012 to 62.4% in 2022, which has provided strong kinetic energy for the high-quality development of agriculture. Science and technology are the fundamental way to stabilize and increase grain production. All regions and departments are guided by tackling key agricultural core technologies and oriented by industrial demand, focusing on chassis technology, key agricultural machinery and equipment, and constantly strengthening agricultural science and technology support.

　　With the support of science and technology, farming will become a "smart farming". Modern information technologies such as the Internet of Things, big data and Beidou navigation have been accelerated in planting production, and technologies and equipment such as precision sowing, smart irrigation and plant protection drones have been widely promoted. Sending skills to the fields and serving the villages, nearly 500,000 agricultural extension workers in China play an irreplaceable role in stabilizing grain supply, increasing production and income. A new technology has landed, and the fields are full of scientific and technological kinetic energy, highlighting the hard support of the "golden pole" of agricultural modernization. With the help of science and technology, agricultural production is constantly improving quality and efficiency.

　　1 billion mu　

　　Built-up area of high standard farmland　

　　Cultivated land is the lifeblood of food production, and farmland construction is a key measure to consolidate the foundation of food security in all directions. In recent years, with the joint efforts of various regions and departments, the work of farmland water conservancy has been solidly promoted, and the construction of high-standard farmland has been steadily accelerated, which has played an important role in ensuring the stable and safe supply of grain and important agricultural products. By the end of 2022, a total of 1 billion mu of high-standard farmland had been built in China, thus ensuring a stable grain production capacity of more than 1 trillion Jin, providing a basic support for ensuring a stable and safe supply of grain and important agricultural products. In the first ten months of this year, about 60.5 million mu of high-standard farmland construction was completed nationwide.

　　High-standard farmland has strong ability to preserve soil, fertilizer and water, and the average grain yield per mu is generally increased by 10%-20%, with high and stable yield, drought and flood, and green planting … At present, the quality of cultivated land in China has entered a stage of continuous improvement and overall improvement.

　　Insist on storing grain on the ground and storing grain in technology, vigorously promote the construction of farmland water conservancy and high-standard farmland in all localities, and continuously improve the quality of cultivated land, laying a solid foundation for ensuring national food security and accelerating the construction of an agricultural power.

　　73%　

　　Comprehensive mechanization rate of farming and harvesting　

　　Advanced mechanical equipment is an important material basis for storing grain in technology. At present, the comprehensive mechanization rate of crop cultivation and harvest in China has exceeded 73%, with 1.8 million sets of agricultural machinery and equipment equipped with Beidou positioning operation terminal, and the foundation of granaries in big countries has been continuously consolidated.

　　Agricultural mechanization has brought about changes in production methods. Sprinkle the medicinal plant protection drone, and you can apply fertilizer accurately by clicking the screen of the mobile phone; The electric-driven high-performance seeder cooperates with Beidou navigation and driving, and the linear error is less than 2.5 cm … In the sky, in the ground and in the internet, all kinds of intelligent agricultural machinery and equipment "show their talents", and mobile phones have become "new farm tools".

　　Agricultural mechanization is an important guarantee for grain saving and loss reduction. In the past, harvesting wheat by hand was time-consuming and laborious, and the loss was 5%-8%. Nowadays, the average harvest loss under normal conditions is only about 1%, and the new intelligent Beidou navigation combine can further reduce the harvest loss.

　　At present, agricultural mechanization is accelerating from the cultivation and harvesting of main crops to the whole process of grain production such as straw treatment and drying. Vigorously promote agricultural mechanization and intelligence, and insert the wings of science and technology into agricultural modernization.

　　23 million people　

　　Number of rural practical talents　

　　The key to rural revitalization lies in people. At present, there are more than 23 million rural practical talents in China, of which 8 million have cultivated high-quality farmers. In recent years, the demonstration and driving ability of rural practical talents has been continuously enhanced, and more and more high-quality farmers have joined the vast countryside. In 2022, the proportion of high-quality farmers who obtained the titles of peasant technicians and national vocational qualification certificates increased by 6.64 percentage points and 3.46 percentage points respectively compared with that in 2021. The participation of a large number of new forces such as college graduates and migrant workers has promoted the continuous improvement of the rural talent team structure.

　　At present, all localities and departments actively build nests to attract phoenix, strengthen the combination of local training of rural talents and external introduction, implement talent engineering projects, increase policy support, optimize the entrepreneurial environment and corresponding services, and guide more talents who love agriculture, understand technology and are good at management to join modern agriculture and rural construction. We will implement the project of cultivating "Head Goose" for rural industry revitalization leaders, carry out training for rural practical talents, further give full play to the leading role of high-quality farmers in the fields of agriculture, rural areas and farmers, and inject new kinetic energy into rural comprehensive revitalization.

　　96%　

　　Coverage rate of improved varieties of crops　

　　Seed is the "chip" of agriculture, and improved varieties play a key role in promoting grain production. In recent years, the revitalization of seed industry has been solidly promoted and a number of breakthrough results have been achieved. At present, the coverage rate of improved varieties of crops in China is over 96%, the contribution rate of improved varieties in agricultural production is over 45%, and the area of self-selected varieties accounts for over 95%.

　　This year is the third year of seed industry revitalization in China. As of October, more than 530,000 germplasm resources of crops, livestock and poultry and aquatic products have been newly collected in China, and the "national team" of improved seed breeding consisting of 216 crop seed production bases and 300 livestock and poultry breeding stations has improved its seed supply support capacity from 70% to 75%. Generally speaking, China’s seed science and technology has been at the advanced level in the world. This year, all localities focused on promoting high-oil and high-yield soybean varieties, the quality of soybeans was significantly improved, and the variety structure was further optimized.

　　Promoting the revitalization of seed industry for a long time. It is necessary to give further play to the institutional advantages, accelerate the self-reliance and self-reliance of high-level seed industry science and technology, guide resource elements to gather in seed industry enterprises, and realize the modernization of the whole industry chain of seed industry.

　　6.2 million　

　　Number of new agricultural management entities　

　　Strong management system is one of the important characteristics of a strong agricultural country. By the end of September this year, there were more than 2.21 million farmers’ cooperatives and nearly 4 million family farms, and the number of new agricultural business entities reached 6.2 million. More than 1.07 million organizations have provided socialized services and become farmers’ intimate "field nannies", serving more than 91 million small farmers, covering over 1.97 billion mu.

　　Organize the advantages of farmers to appear. Farmers’ cooperative members take farmers as the main body, organize small farmers to carry out specialized production and large-scale operation on the basis of stabilizing the contracted management of farmers’ families, and cooperate to break into the market, thus effectively improving the efficiency of agricultural operation. As an effective organizational form to develop moderate scale management and modern agriculture under the market economy, cooperatives and family farms give new connotations to the two-tier management system and inject vigorous vitality into the rural basic management system.

　　Service-driven ability is enhanced. The business scope of cooperatives and family farms covers the production of major agricultural products such as grain, cotton, oil, meat, eggs, milk, fruits and vegetables, tea, etc., and has carried out contiguous planting and large-scale feeding, making a number of advantageous industries with "township name" and "local name" bigger and stronger, and promoting the integrated development of rural primary, secondary and tertiary industries.

　　"Relying on the scientific research achievements resources and talents’ technical advantages of the units where the science and technology commissioners are stationed, we have accelerated the transformation and industrialization of modern agricultural scientific and technological innovations, and hatched and cultivated a number of high-value &rsquo; Agricultural enterprises with high added value. "

　　In Yongchun Zhihui Valley, Xingchuang Tiandi, Fujian Province, Lin Zhirong, a college student, has grown from an entrepreneurial "Xiaobai" who is responsible for the new media promotion of health tea projects to a maker who runs two tea online stores in partnership, realizing a wonderful "turn" in life.

　　This is due to Zhihui Valley’s "helping hand": under the guidance of Zhihui Valley’s entrepreneurial tutor and Associate Professor Zheng Shuangyang of Jiangxia College, with the help of Zhihui Valley platform resources, Lin Zhirong’s project signed a number of tea gardens, and after only six months of operation, it has achieved profitability. In January this year, the turnover of a single store exceeded 100,000 yuan. This is a microcosm of the construction of Xingchuang Tiandi in Quanzhou. Up to now, the city has cultivated 37 star-creation worlds at all levels, including 13 national ones, ranking first in the province in total.

　　"Facing the needs of rural agricultural development in the new era, Quanzhou has played the role of science and technology Commissioner &lsquo; Mechanism activity &rsquo; , constantly explore new modes of innovative science and technology commissioners’ work, take the lead in extending the service of science and technology commissioners to secondary and tertiary industries in the province, support science and technology commissioners to participate in the construction of Xingchuang Tiandi, accelerate the transformation and industrialization of modern agricultural science and technology innovation achievements by relying on the scientific research resources and talent technology advantages of the units where science and technology commissioners are stationed, and incubate and cultivate a number of ornamental and medicinal plant industries such as Anthurium andraeanum and Cymbidium, with &lsquo; Gao Yan value &rsquo; Agricultural enterprises with high added value will further promote the innovation and entrepreneurship actions of science and technology commissioners. " Li Wensheng, director of Quanzhou Science and Technology Bureau, said.

　　Build a platform and build an agricultural cooperation exhibition field between Fujian and Taiwan

　　Located in quanzhou taiwanese investment zone, Taiwan Province Agricultural Technology Exchange and Promotion Center, the first national agricultural cooperation and promotion platform between Fujian and Taiwan in China, has exchanged and cooperated with well-known agricultural universities such as Taiwan Province University, Chiayi University and Zhongxing University all the year round; Relying on the construction of Quanzhou Academy of Agricultural Sciences, it is the first to carry out the work of corporate science and technology commissioners in the province, docking high-end resources such as academician workstations, and providing "one-on-one" training and guidance services &hellip; &hellip; Entering the first batch of national stars to create heaven and earth &mdash; &mdash; Quanzhou agricultural science and technology star creates a world, and a series of "soft and hard facilities" provided for settled enterprises and makers attract attention.

　　As the earliest enterprise introduced by Xingchuang Tiandi, which specializes in producing ornamental plant Anthurium, Fengquan Agriculture is benefiting from this. "Enterprises connect with Tang Hongling and Zhang Peng through the platform, introduce famous varieties of Anthurium, innovate supporting agricultural facilities, etc., and improve the quantity and quality of finished flowers. The flowering period is extended by 10 to 15 days year-on-year, which effectively improves the competitiveness of enterprise products." Chen Yilong, head of Fengquan Agriculture, said.

　　"By building the platform of Xingchuang Tiandi, we will build a bridge between scientific and technological achievements and makers, which will not only guide innovation and entrepreneurship such as special projects, but also strengthen technical cooperation with settled enterprises, and transform while researching, greatly shortening the agricultural scientific research achievements to &lsquo; Field &rsquo; Distance, promote the popularization and application of agricultural technology and excellent crop varieties. " Zhuang Weidong, director of Quanzhou Academy of Agricultural Sciences and head of Quanzhou Agricultural Science and Technology Xingcheng Tiandi, said.

　　At present, Xingchuang Tiandi provides services for the whole process of incubation, cultivation and entrepreneurship of agricultural high-tech enterprises nationwide. Under its matchmaking, Fujian Jisheng Pigeon Industry Co., Ltd., a settled enterprise, has reached a cooperation agreement with Taiwan Province Youhui Biotechnology Co., Ltd., in order to further develop the market. Over the past year or so, 15 start-ups have rushed to settle in, and there is an endless stream of incubator seekers.

　　Promote transformation and tap new kinetic energy of characteristic industries

　　Nan ‘anhui Sweet Bee Family Farm, located in Xiangyang Township, Nan ‘an City, Quanzhou, is full of numbered beehives. "You can’t take too much honey in autumn. You should leave enough rations for bees in each box to ensure the survival rate in winter." Under the careful guidance of Professor Zhou Bingfeng of Fujian Agriculture and Forestry University, director of the National Bee Industry Technology System Feeding and Machine Function Research Office of Fujian Agriculture and Rural Affairs Department, the farm has developed and bred 500 colonies of undergrowth bees, with an annual output of 25,000 kilograms of honey and an annual output of 1.5 million yuan. Under-forest beekeeping has also become a characteristic industry to drive local farmers out of poverty and become rich.

　　Previously, as a relatively poor township in Nan ‘an, Xiangyang Township had few agricultural products sales channels, low per capita income and many poor households. Zhou Bingfeng found in the field investigation that the township is surrounded by mountains and the forest coverage rate is as high as 90%, which has a unique advantage in developing bee breeding and bee culture industry. Therefore, Zhou Bingfeng teamed up with Dushan Ecological Agriculture and Forestry Cooperative in Nan ‘an City and Nan ‘an Hui Sweet Bee Family Farm to carry out Industry-University-Research cooperation, and took the lead in creating the first Xingchuang Tiandi focusing on bee entrepreneurship in Fujian &mdash; &mdash; Huitian Bee Industry has created a new world, promoted the application of new technologies such as large-scale breeding of Chinese bees and healthy and efficient breeding of Chinese bees in the national bee industry technology system, and promoted the improvement of the local Chinese bee breeding technology level and the development and growth of the bee industry.

　　While providing entrepreneurial counseling and incubation services for the bee industry, Xingchuang Tiandi also provided free bee colonies, beehives and breeding technical materials to poor households with established cards, and signed an agreement to purchase bee products, driving 51 poor households to develop bee breeding to get rid of poverty and become rich. Up to now, Huitian Bee Industry Xingchuang Tiandi has settled in 32 agricultural enterprises, successfully hatched 10 enterprises and 44 entrepreneurial teams, including 40 entrepreneurial teams from poor households. The new agricultural business entities cultivated have created economic benefits of 50 million yuan every year.

　　Excavate new kinetic energy from traditional industries and discover new possibilities from emerging industries. In Quanzhou, relying on superior resources, there are many examples of introducing special departments to take the lead in building Xingchuang Tiandi and developing rural characteristic industries. For example, Anxi Tengyun Station Xingchuang Tiandi makes full use of the radiation of Taobao Town and Taobao Village, integrates resources through Xingchuang Tiandi, optimizes the combination of scattered family-owned workshops, promotes the transformation and upgrading of traditional industries, and makes rattan and iron technology production become the leading enterprise and pillar industry in Shangqing Township.

　　Huang Zhenxia, a researcher of Quanzhou Science and Technology Bureau, said that Xingchuang Tiandi has applied modern agricultural concepts to the transformation and upgrading of the whole agricultural industry chain, focused on cultivating new agricultural business entities, supported the development of new industries, new formats and new models, and promoted the development of traditional agriculture to "internet plus" modern agriculture, circular agriculture and leisure agriculture, and has continuously become a new force to promote the transformation and upgrading of Quanzhou’s agriculture.

　　Leading the way, cultivating "new farmers" who strengthen agriculture and promote agriculture

　　"Focus on building a high-quality agricultural science and technology innovation and entrepreneurship service platform. In addition to cultivating college students’ new entrepreneurs, Zhihuigu also supports entrepreneurs such as returning migrant workers and rural youth leaders who become rich, and stimulates more enthusiasm for innovation, entrepreneurship and wealth creation of agriculture-related enterprises." You Changsheng, head of Yongchun Zhihui Valley, said.

　　According to him, at present Zhihui Valley is connected with provincial-level science delegations and associate professor Wang Mingyuan of Huaqiao University, and together with provincial, municipal and county resident cadres in Penghu Town, Yongchun, it has created a "shared poverty alleviation station" to create a shared platform for local agricultural and sideline products to integrate production and marketing, and to change "blood transfusion" poverty alleviation into "hematopoietic" poverty alleviation, helping precision poverty alleviation work.

　　Behind the vitality of Zhihui Guxing’s creation of the world, there is a strong backing, the local leading agricultural enterprise and the demonstration base of Quanzhou science and technology correspondent &mdash; &mdash; Quanzhou jinsheng ecological agriculture co., ltd. The enterprise built Quanzhou Anoectochilus roxburghii Enterprise Engineering and Technology Research Center, and innovated the techniques of sexual propagation of Anoectochilus roxburghii seedlings and imitation of wild ground cultivation under the forest. Compared with the traditional anoectochilus roxburghii produced by asexual propagation, it is more authentic and has higher nutritional value. The cultivation has driven a group of makers like Lin Zhirong to settle in Zhihui Valley Xingcheng Chuangtiandi.

　　This is another innovative measure of Quanzhou’s layout of Xingchuang Tiandi: make full use of the technical strength of science and technology commissioners, make use of the advantages of capital, manpower, technology, market and management of leading enterprises to build Xingchuang Tiandi, give play to its radiation-driven role, and build a group of "new farmers" who understand agriculture, love the countryside and love farmers, and help win the tough battle against poverty.

　　Li Wensheng said that in the next stage, Quanzhou will take Xingchuang Tiandi as an important starting point for scientific and technological work, promote the seamless connection between the system of science and technology commissioners and encouraging mass entrepreneurship and innovation, further stimulate the vitality of rural innovation and entrepreneurship, build a Xingchuang Tiandi platform suitable for Quanzhou’s development, provide rural science and technology entrepreneurship services for college students and returning migrant workers, promote the integrated development of primary and secondary industries, and drive millions of farmers to increase their income and become rich.

　　It is understood that since 2016, Quanzhou Science and Technology Bureau has gathered 392 entrepreneurial teams, 211 entrepreneurial mentors, served 370 start-ups and held 415 innovative and entrepreneurial activities by cultivating Xingchuang Tiandi. It is planned that by the end of 2020, Quanzhou will strive to cultivate 40 star-creation worlds at all levels and gather 5,000 talents of various scientific and technological innovations, and basically form an agricultural and rural innovation system with popular entrepreneurial subjects, diversified incubation objects, professional entrepreneurial services, networked organizational systems and market-oriented construction and operation.

Machine heart report

Editor: Chen Ping, Du Wei

Have you ever seen a drone that can withstand a strong gust? Researchers at the California Institute of Technology use deep neural networks to make drones no longer afraid of the wind.

When the wind is strong enough to blow out the umbrella, the drone is steady, like this:

Flying against the wind is a part of air flight. On a large scale, when pilots land their planes, the wind speed may bring them challenges. On a small scale, gusts will also affect the flight of drones.

At present, drones either fly under controlled conditions and have no wind; Or operated by humans using a remote control. Unmanned aerial vehicles are controlled by researchers to fly in formation in the open sky, but these flights are usually carried out under ideal conditions and environments.

However, in order for UAVs to perform necessary but daily tasks autonomously, such as delivering packages, UAVs must be able to adapt to wind conditions in real time.

In order to make the UAV have better maneuverability when flying in the wind, a group of engineers from California Institute of Technology developed a deep neural network Neural-Fly, an artificial intelligence tool, which can keep the UAV agile in windy conditions, and only need to update some key parameters to help the UAV cope with new and unknown wind conditions in real time.

At the beginning of the article, we have seen the wind resistance of the UAV. The following shows a quadrotor UAV. With the help of the tool developed by this research, it can complete the figure-eight shuttle operation when the wind speed reaches 27 mph:

Watch the drone flying against the wind from another angle;

In order to allow the UAV to shuttle in various wind speeds, data is essential. This research needs little data. After obtaining the flight data in just 12 minutes, the automatic quadrotor UAV equipped with Neural-Fly learned how to respond to strong winds. "The amount of data used is very small," said Michael O’Connell, a graduate student in the Department of Aeronautics and Astronautics at California Institute of Technology and one of the authors of the paper.

The study was published in the journal Science Robotics on Wednesday.

Address: https://www.science.org/doi/10.1126/scirobotics.abm6597.

ArXiv Address: https://arxiv.org/pdf/2205.06908.pdf

In the Neural-Fly experimental training, the UAV flies in the wind tunnel with six different wind speeds, the fastest of which is 13.4 mph.

Based on these data, the team created a deep neural network, and then enabled their aircraft to skillfully maneuver in the same wind tunnel, such as enlarging the gate in a figure-of-eight pattern or cruising through two oval gates. The speed of the drone in the test is faster than it encountered in the training: about 27 miles per hour. This is the maximum wind speed that the wind tunnel can produce, pointed out Shi Guanya, the author of this paper and a graduate student of California Institute of Technology. Except that only a small amount of data is needed, the software only runs on Raspberry Pi, which is a cheap computing device.

Soon-Jo Chung, a professor of aerospace, control and dynamics systems at California Institute of Technology and a correspondent, said that the error rate they saw was 2.5 to 4 times better than that of the existing SOTA technology.

The picture below shows Shi Guanya, Soon-Jo Chung and Michael O’Connell from left to right. Congratulations, Shi Guanya will join the Robotics Institute of Computer College of Carnegie Mellon University as an assistant professor in September 2023.

The researchers said that this technology will be used for drone express delivery or flying cars in the future.

Overview of Neural-Fly technology

If unmanned aerial vehicle (UAV) wants to realize continuous commercialization, it is very important to perform safe and accurate flight maneuvers in dynamic high-speed wind. However, because the relationship between different wind conditions and their influence on the maneuverability of UAV have not been deeply studied, it is challenging to design an efficient robot controller using traditional control design methods.

"Neural-Fly" proposed by researchers of California Institute of Technology is a data-driven method. As a trajectory tracking controller based on deep learning, it can learn to adapt to rapidly changing wind conditions. Figure 3(A) below shows the data collection process; 3(B) When the wind speed is 13.3km/h (3.7m/s), input and label the training data; 3(C) is the distribution of input data and label data under different wind conditions.

On-line Adaptive+Off-line Meta-learning

Figure 2 below is an overview of the Neural-Fly method, which shows that it has made progress in adaptive flight control and robot control based on deep learning. Under the dynamic wind conditions of standard UAV, Neural-Fly can track the centimeter-level position error of flexible and challenging trajectory. Specifically, this method mainly consists of two parts, namely, offline learning stage and online adaptive control stage for real-time online learning.

For the off-line learning stage, the researchers developed Domain Adversarial Invariant Meta-learning (DAML), which learned the expression of deep neural network (DNN) which is independent of wind conditions in a data-efficient way. This representation adapts to different wind conditions by updating the linear coefficients of a set of mixed depth neural network outputs.

DAIML also has data efficiency, and only 12 minutes of flight data under six different wind conditions are used to train the deep neural network. DAIML contains several key features, which can not only improve data efficiency, but also provide information by the downstream online adaptive control stage.

It is worth noting that DAIML uses spectral normalization to control the Lipschitz property of deep neural network, so as to improve the generalization ability of unknown data and provide closed-loop stability and robustness. In addition, DAIML also uses discriminant network to ensure that the learned representation is wind-invariant, and the wind-related information is only included in the linear coefficient that adapts to the online control stage.

For the on-line adaptive control stage, researchers developed a regularized compound adaptive control law, which is based on the basic understanding of how the learned representation interacts with the closed-loop control system and has strict theoretical support.

Specifically, the adaptive law uses the combination of position tracking error term and aerodynamic prediction error term to update the linear coefficient related to wind. This method effectively ensures the stability and rapid adaptation to any wind conditions and the robustness to imperfect learning. Although this adaptive control law can be used with many learned models, the accurate representation learned from DAIML is helpful to further improve the adaptive speed.

experimental result

As far as the effect of Neural-Fly is concerned, it is 66% higher than that of nonlinear tracking controller, 42% higher than that of L_1 adaptive controller and 35% higher than that of incremental nonlinear dynamic inversion (INDI) controller. All these results are achieved by using standard quadrotor UAV hardware, and the default attitude control of PX4 is running at the same time.

The tracking performance of Neural-Fly is competitive even compared with related work without external wind interference and using more complicated hardware (such as on-board optical sensor that needs 10 times control frequency and uses DC motor speed feedback).

Table 1 below shows the error tracking statistics of different methods under different wind conditions.

The researchers compared Neural-Fly with two variants, namely Neural-Fly-Transfer and Neural-Fly-Constant. Among them, NF-Transfer uses representations trained from data of different UAVs, while NF-Constant only uses adaptive control laws with trivial non-learning basis.

Neural-Fly-Transfer shows the robustness to UAV configuration changes and model mismatch. NF-Constant, L_1 and INDI methods all directly adapt to unknown dynamics without assuming the underlying physical structure, and they have similar performance.

Finally, the researcher proves that Neural-Fly can realize a series of functions, allowing the UAV to follow the trajectory and fly over the low-altitude door quickly under the condition of strong wind, as shown in Figure 1 below.

　　Zhongxin. com Sichuan News, January 4th (Liu Xiaoli) At the beginning of the new year, all enterprises in China Sichuan Cuisine Industrial City Park, Pidu District, Chengdu are busy with production, R&D, market expansion and order rush, striving to achieve a "good start" in the first quarter.

　　On January 3, the production workshop of Novomey Biotechnology Chengdu Co., Ltd. (hereinafter referred to as Novomey) was busy. In the frying workshop, 40 woks are arranged around, and the staff are monitoring all data indicators in real time in front of the electronic screen; In the packaging workshop, the equipment runs quickly, and bags of compound seasoning are off the assembly line. In the loading and unloading area, the packaged products are being loaded and will be sent to major cities soon.

　　Nuogaomei Company is a comprehensive standardized condiment customization enterprise integrating R&D, production and sales, focusing on providing catering enterprises with the overall solution of catering standardization in compound seasoning. The enterprise was built last year and put into production in October last year. Since it was put into production, it has been in busy production.

　　"Before and after the Spring Festival is the traditional peak season for consumption, and it is also the peak season for production in the food industry. Our company’s philosophy is’ everything must serve customers’, so we are working hard to ensure the delivery of orders. " Ni Taoyuan, the production director of Novomey, said that at present, there are enough orders from enterprises. In order to ensure delivery, the frying workshop runs 24 hours a day, and the staff takes two shifts and all 40 woks run. "The frying workshop can guarantee the delivery of 200 tons of fried materials every day, and the whole factory can deliver 300 to 400 tons every day."

　　According to reports, as a professional service provider providing compound seasoning for chain catering brands, Nogo Beauty Company has been quietly appearing beside consumers. Everyone’s familiar delicacies, such as Man Xiaobao, Shu Daxia, Mao Daxian, Laoxiang Chicken, Wuliguan Hot Pot, Limestone Roast Chicken, and Laojie Weigan String, are all inseparable from Nuogaomei.

　　"We will use Nogomel as the company headquarters, and at the same time, we will transfer the production capacity of the company in other regions to China Sichuan Food Industry City." The person in charge of the company said that through the creation of smart factories, we will strive to achieve new breakthroughs in output value.

　　Not far from Nogaomei Company, Sichuan Dandan Pixian Douban Group Co., Ltd. (hereinafter referred to as Dandan Group) Sichuan Road Factory is also busy, and the workers cooperate closely with each other to make orders and sprint for a "good start".

　　"At present, there are still many orders, and we are in a hurry. Roughly speaking, from New Year’s Day to Spring Festival, we need to deliver orders of more than 80 million yuan. At present, we are working at full capacity and working overtime to ensure market supply before the holiday. " Yue Yisong, Marketing Director of Dandan Group, said.

　　According to reports, the Sichuan Road Factory of Dandan Group has been running well since it was put into production, and its production capacity has been fully released. However, it is still far from meeting the market demand. Yue Yisong introduced that in order to solve the problem of tight production capacity, in early 2023, the company built a new production workshop in Yong ‘an Road Factory. It is expected that this workshop will be put into use in 2024, which will alleviate the problem of supply capacity to some extent.

　　In 2023, Dandan Group shouldered the market pressure, strove forward and operated steadily, and achieved a booming production and sales. The annual sales revenue exceeded 800 million yuan, up more than 15% year-on-year. Yue Yisong said that in 2024, Dandan Group will, as always, do a good job in products and services, continue intensive cultivation to expand the market, increase the application and promotion of Pixian watercress in various cuisines, and intensify brand promotion, so as to make a good start for Dandan Group’s journey towards 1 billion yuan.
