　　The double standards and hegemonic acts of the United States in the field of human rights are well known. In recent years, the United States has extended hegemonism to the field of science and technology, under the banner of so-called democracy, human rights, freedom and security, and achieved the goal of putting its own interests above those of other countries by such despicable means as unwarranted accusations, "long-arm jurisdiction", suppression of sanctions and targeted technical blockade of other countries. The hegemonism of science and technology pursued by the United States is a typical manifestation of its consistent concept of "American priority". Its hegemonic behavior of politicizing, weaponizing and ideologizing scientific and technological issues not only seriously damages the "digital human rights" of other countries, but also hinders global technical cooperation and progress.

　　Engage in "small circles" on the grounds of so-called "network security" to create division and confrontation.

　　Influenced by the deep-rooted zero-sum thinking and the Cold War thinking, the United States has always handled international relations in a split and confrontational way, constantly creating "small circles" of science and technology such as "chip alliance" and "clean network" on the pretext of so-called "network security", labeling high technology as democracy and human rights, and looking for excuses to impose technological blockade on other countries.

　　In the name of democracy, the United States maintains the hegemony of science and technology, and launches various technical alliances with democracy as the ideological link and network security as the goal, such as Prague Proposal and 5G Clean Path. In April 2022, the United States and 60 global partners issued the Declaration on the Future Internet, with the real intention of delineating a "net in the net" or a "digital alliance" led by the United States in the global Internet. The United States has also pushed the private sector to strengthen technology blockade and build technology fences, trying to contain competitors by means of sanctions and bans, which has seriously hindered exchanges and cooperation, development and progress in the global scientific and technological field.

　　Using the so-called "public safety" as an excuse to wantonly monitor and infringe on privacy.

　　The United States has always been the world’s number one telecom thief, and its monitoring targets include not only so-called "sensitive people" but also ordinary people in the country; There are not only so-called opponents, but also their allies, even the leaders of the allies.

　　In the first half of 2022, the US military and government network departments remotely stole more than 97 billion global Internet data and 124 billion telephone records in nearly 30 days, involving the personal privacy of a large number of citizens around the world. According to the annual report released by the Office of the Director of National Intelligence on April 29th, 2022, the FBI conducted as many as 3.4 million searches on the electronic data of the American people in one year without a search warrant.

　　In fact, since the middle of the 20th century, the United States has a record of monitoring other countries. In the information age, the United States has gone to great lengths to implement a number of eavesdropping and stealing projects, such as Prism Gate, Dirty Box, Nujiao Plan and Telescreen Action. Various eavesdropping and stealing methods have emerged one after another, including using analog cell phone base station signals to access mobile phones to steal data, manipulating mobile phone applications, invading cloud servers, and stealing secrets through submarine optical cables.

　　According to the German weekly Der Spiegel, from 2003 to 2013, the Office of Specific Invasion Operations under the US National Security Agency invaded 258 targets in 89 countries and regions. Over the years, the office has also carried out tens of thousands of malicious attacks on network targets in China. For example, in the cyber theft attack on Northwestern Polytechnical University, 54 springboard machines and proxy servers in 17 countries were used successively, with more than 1,100 attack links and as many as 41 kinds of special cyber attack weapons and equipment of the National Security Agency of the United States. The eavesdropping behavior of the United States has already caused public outrage in the international community.

　　Technical blockade under the pretext of so-called "technical security" damages the right to development.

　　For some time, the United States has spared no effort to put different political labels on the R&D, use and governance of emerging technologies and the supply chain of scientific and technological products. By dividing the so-called "safety trust level", publishing a series of lists and building a technological ecosystem under the so-called "credible" standards, the United States has abused scientific and technological hegemony to suppress competitors, which has seriously damaged the development rights of other countries.

　　In November 2018, since the implementation of the so-called "China Action Plan" in the United States, Chinese scientists have been harassed, monitored and attacked by the American government for no reason, and various bad and absurd acts of law enforcement departments have been exposed by the media. Although the plan was stopped in 2022 in the voice of doubt and opposition, the hegemonic behavior of the United States "only allowing itself to develop and not allowing others to progress" has not ended. The United States promulgated the Chip and Science Act and a series of new export control regulations for China in an attempt to restrict China’s ability to acquire advanced computing chips, develop and maintain supercomputers and manufacture advanced semiconductors.

　　Ignoring or denying the scientific and technological sovereignty, people’s interests and development demands of other countries and regions, the United States attempts to take its lead in the allocation of network resources, hardware equipment and software applications as a hegemonic strategic tool by refusing competition, grabbing wealth, exporting ideology and squeezing the space for scientific and technological development in other countries around the world, which not only seriously hinders other countries from using new technologies, but also further widens the trust gap in global digital space security, undermines the global industrial chain layout and scientific and technological order, and violates the laws of global scientific and technological development.

　　The French philosopher Saint-Simon once said: "For all mankind, there is only one common interest, and that is the progress of science." Scientific and technological innovation is an important engine for the development of human society, and scientific and technological achievements should benefit all mankind. Hegemonism in science and technology poses a new threat to world peace and development. The international community should recognize the hypocritical nature of American technological hegemonism, jointly resist American arrogance, prejudice and hegemonic behavior of technological hegemony, jointly respond to all kinds of cyber attacks, and maintain a peaceful, safe, open, cooperative and orderly cyberspace.

　　The project team carried out comprehensive and systematic research and development, and the new technical achievements developed effectively extended the shelf life of fruits and vegetables by reducing the original pollution of spoilage bacteria in vegetables, preventing the rapid propagation of spoilage bacteria, and dynamically adjusting the gas atmosphere in the packaging microenvironment.

　　With the increasing variety of food ingredients and the changes of climate and environment, traditional preservation methods can no longer meet the deeper preservation needs.

　　On May 8th, the reporter of Science and Technology Daily learned from Jiangnan University that the research team of Yao Weirong, a professor at the School of Food Science, tackled the problem of perishable storage of fresh fruits and vegetables, and successively developed cleaning and disinfection technologies (ultrasonic technology, natural plant-derived cleaning disinfectant), new cold sterilization technologies (low-temperature plasma technology, irradiation technology), as well as preservative and active packaging film, which have been fully applied in domestic fruit and vegetable bases and storage and transportation industries.

　　According to Chen Wei, academician of China Academy of Engineering and president of Jiangnan University, people’s food needs are increasingly diversified. Applying modern technology to solve the storage problem of fresh fruits and vegetables will play an important role in ensuring market supply and promoting rural revitalization.

　　Yao Weirong introduced that leafy vegetables are easy to rot, mainly due to high water content, vigorous physiological activities after picking, high pollution of original microorganisms and high requirements for storage conditions. Therefore, relevant preservation measures must be taken in order to adjust the storage conditions such as temperature, air humidity and gas atmosphere.

　　In order to prevent fresh vegetables from rotting, most of them are stored in cold storage. In recent years, although there are more and more quick-frozen vegetables, this method usually requires blanching pretreatment first, which is easy to cause the loss of minerals and vitamins.

　　Chen Wei introduced that the food consumption structure of urban and rural residents in China was dominated by coarse grain consumption at first, and now it is rapidly transforming into a diet structure in which vegetables, fruits, meat, milk, eggs and other livestock products, aquatic products and processed foods coexist. This change makes people eat more safely, healthily and with balanced nutrition.

　　At present, the most effective ways to store vegetables in the world are mainly modified atmosphere preservation and irradiation preservation, which can inhibit the growth of microorganisms or vegetable tissues by improving the composition of environmental gases and using irradiation respectively, and have the effect of killing insects and sterilizing.

　　"Our team has carried out comprehensive and systematic research and development, and the new technological achievements have effectively extended the shelf life of fruits and vegetables by reducing the original pollution of spoilage bacteria in vegetables, preventing the rapid propagation of spoilage bacteria, and dynamically adjusting the gas atmosphere in the packaging microenvironment." Yao Weirong said.

　　The reporter learned that in January this year, the "magnetic field preservation technology" jointly developed by Jiangnan University and TCL passed the project technical appraisal meeting organized and hosted by China National Light Industry Federation. This indicates that China has broken the foreign monopoly of molecular preservation technology, and has stepped into technology leadership from technology catch-up.

　　According to relevant experts, the molecular preservation technology is to use magnetic field induction to realize unlimited micro-vector preservation, so that the ingredients can achieve the 6-day preservation effect of moistening, nourishing, beautifying, cleaning, living and fresh. This is because water molecules, organic compounds and biological macromolecules all belong to diamagnetic materials, so they will induce external magnetic fields.

　　At present, this latest technological achievement of integration of production and education, which has multiple functions of water locking, antioxidation and bacteriostasis, has been applied in China.

　　In Yao Weirong’s view, these technologies can basically solve the problem of fresh fruit storage. However, technology alone can’t do without paying attention to application and storage methods.

　　At present, it is still difficult for some agricultural production bases and storage and transportation enterprises to package and store all kinds of vegetables in a targeted way. In order to reduce costs, transportation and storage often enter the transportation and storage process by extensive and simple dressing, and there is no independent packaging at all, resulting in vegetables not being well protected.

　　Especially for all kinds of vegetables transported in large quantities, vegetables will squeeze each other, causing artificial mechanical damage, which accelerates the decay and deterioration of fruits and vegetables and causes serious waste.

　　Chen Wei believes that there are still some problems to be solved in promoting the high-quality and differentiated development of agricultural products and food industries in China. Among them, how to ensure the effective market supply of various foods such as meat, vegetables, fruits, aquatic products, etc., it is urgent to make efforts from the technical end and the supply end to open up the "last mile" from farmland to the dining table, so that the latest scientific and technological achievements can be widely used to further meet the needs of consumers for food diversification, refinement, nutrition and ecology.
