This is of great strategic significance for promoting the independent innovation and industrialization of China's next-generation Internet core equipment.

Second, China Petrochemical Co., Ltd. announced on April 3rd that Puguang gas field, the largest and most abundant offshore gas field in China, was discovered in northeast Sichuan. Approved by the Mineral Resources Reserve Evaluation Office of the Ministry of Land and Resources, Puguang Gas Field has accumulated proven recoverable reserves of 2510.75 billion cubic meters and technically recoverable reserves of/kloc-0 1.8830.4 billion cubic meters. The discovery of Puguang gas field is of great significance to the development strategy of China Petrochemical resources, and also plays a positive role in alleviating the shortage of oil and gas resources in China.

Third, build the first fully superconducting tokamak nuclear fusion experimental device. The world's first fully superconducting noncircular cross-section tokamak nuclear fusion experimental device (East) was designed and developed by China. In the first round of physical discharge experiment on September 28th, a high temperature plasma discharge with a current of 200 kA and a time of nearly 3 seconds was successfully obtained. The key components of EAST device are independently developed, processed, manufactured, assembled and debugged by the scientific and technical personnel of Institute of Plasma, Chinese Academy of Sciences, all of which meet or exceed the design requirements. The construction of EAST has made China's fusion research take a big step forward, which has been highly valued by the international fusion community.

Fourthly, the * * * oscillation phenomenon of chemical reaction is observed at the quantum level. Researcher Yang of Dalian Institute of Chemical Physics, Chinese Academy of Sciences and his colleagues first observed the * * * oscillation phenomenon of the molecular chemical reaction of fluorine hydrogenation with full quantum state resolution in the experiment, which was confirmed by the theoretical model, solved a difficult problem that has not been solved in international chemical research for more than 30 years, and pushed the study of chemical reaction mechanism to a new height and accuracy. The research results were published in the journal Science. Richardson. Zarea, an academician of the American Academy of Sciences and a professor at Stanford University, spoke highly of this achievement of China scientists.

Fifth, the first "green corridor" crossed the Taklimakan Desert. Tarim Oilfield Company of China Oil and Gas Company, Xinjiang Institute of Ecology and Geography of Chinese Academy of Sciences, Institute of Environment and Engineering in Cold and Arid Regions of Chinese Academy of Sciences, and Daqing Oilfield Construction Design and Research Institute completed the "Study on Ecological Engineering Construction of Tarim Desert Highway" on 14 * *. The world's first "green corridor" crossing the flowing desert with a length of 436 kilometers was jointly afforested on both sides of the desert highway on the basis of pilot test by PetroChina and Chinese Academy of Sciences.

Sixth, the first global marine scientific expedition triumphed 65438+1On October 22nd, the "Dayang No.1" scientific research ship completed the first global marine scientific expedition in China after 297 days' voyage. According to the introduction of the State Oceanic Administration, this global marine scientific expedition has a journey of 43,230 nautical miles. More than 100 researchers from more than 20 research institutes participated in this expedition, and obtained a large number of valuable materials and samples for the first time. Global scientific research activities have effectively enhanced China's international status in international seabed regional activities.

Seventh, great progress has been made in the research of therapeutic hepatitis B vaccine. The "therapeutic hepatitis B vaccine" developed by the Third Military Medical University has successfully completed the first phase of clinical research and is currently undergoing the second phase of clinical research. This is the first simulated antigen vaccine used in clinical trials. "Therapeutic hepatitis B vaccine" belongs to a new class of national biological products, and has applied for national invention patents and international invention patents. The "E-gram" vaccine developed by Fudan University and Beijing Institute of Biological Products is preparing to start the third phase clinical trial. These achievements will make an important contribution to controlling the epidemic of viral hepatitis.

Viii. The major reconstruction project of Beijing Electron-Positron Collider was successful 165438+ 10/8. At 7: 20 a.m., the storage ring of Beijing Electron Positron Collider Major Reconstruction Project (BEPCII) successfully realized beam accumulation, the storage ring and linear accelerator worked stably, and the beam performance was good, which means that the second-phase construction task of BEPCII basically reached the goal and was a major milestone in the project construction. Prior to this, on September 19, China's largest single superconducting magnet was successfully developed, and the Beijing Spectrometer ⅲ superconducting magnet was successfully excited. At present, only Europe, America and Japan can develop this single superconducting magnet for large detectors. After the transformation, BEPCII will continue to be the leading equipment of its kind in the world and one of the most advanced double-ring colliders in the world.

Ninth, the research team led by Professor Pan Jianwei of China University of Science and Technology has successfully teleported the quantum state of the two-particle composite system for the first time in the world, and successfully manipulated the six-photon entangled state for the first time. This research paper was published in the journal Nature and Physics and reported on the cover, which is the first time that an article by a scientist from China appeared on the cover of this magazine. The research results have created a new starting point for all kinds of practical quantum information research, and will have a far-reaching impact on important research directions such as fault-tolerant quantum computing, quantum relay and generalized quantum error correction.

Tenth, "Remote Sensing Satellite No.1" was successfully launched. At 6: 48 on April 27th, China successfully launched Remote Sensing Satellite No.1 into the scheduled orbit with the Long March 4 B carrier rocket at Taiyuan Satellite Launch Center. The "Remote Sensing Satellite No.1" and the "Long March 4 B" carrier rocket used to launch satellites were mainly developed by Shanghai Aerospace Technology Research Institute under China Aerospace Science and Technology Corporation, with the participation of China Academy of Sciences, China Electronics Science and Technology Corporation and China Academy of Space Technology. The satellite, with a mass of over 2,700kg, is mainly used for scientific experiments, land and resources investigation, crop yield estimation and disaster prevention and mitigation, and will play an active role in the national economic development of China.
