The project team of the “Strongly Flowing Fusion Neutron Source Scientific Device” project independently designed and developed the powerful neutron fusion neutron source HINEG. The results were evaluated by a panel of academicians consisting of several academicians: “In a similar device, strong currents氘氚 fusion neutron source HINEG neutron source strong in the first in the world, running stable, ultra-high heat-carrying rotating target and other core technologies in the international advanced level. The main innovations of the project are: 1) Innovative design and development of a dual-mode strong neutron fusion neutron source scientific device. The fusion neutron source is the first in transport international. The neutron source scientific device designed based on the new nuclear energy particle transport theory has dual-mode characteristics of fusion neutron source and fission neutron source, and the fusion neutron source is 6.4×1012 n/s. 2) Breakthrough the key technologies of the whole process of constrained continuous generation and accurate measurement and control of strong flow fusion neutrons, and solved the international difficulties in enhancing the source strength of neutrons. Developed a multi-mechanism collaborative enhancement heat transfer method, invented the array jet coupled strong shear flow heat dissipation technology, successfully developed the ultra-high heat-carrying rotating target system carrying heat flux density, and developed a post-magnetic confinement space charge suppression high gradient uniformity Field electrostatic acceleration technology developed an ultra-high voltage and low ripple DC switching power supply; a long neutron counter source intensity measurement technology based on neutron multiplication energy compensation was invented, and the energy response was broadened to more than 20 MeV. 3) The innovation is applied to reactor core simulation and neutron physics experiment verification, and the first international instrument stack reactor core isomorphic neutron physics experimental device is built. Invented a modular core consisting of a flexible combination of honeycomb structure components, developed a multi-dimensional redundant complex coupling system control strategy, and realized multi-type reactor stacks such as lead-based fission reactors, fusion fission hybrid reactors, and accelerator-driven subcritical reactors. Isomorphic simulation of the core.

The “Project on Key Technologies for Sport Promotion Health Cloud Services and the Construction of a Closed-loop Service System” is aimed at the national strategic needs of the nation’s health. It has established a joint research team of medical and biomedical engineering and information technology, and initiated the innovation movement to promote the theoretical system of health from the perspective of methodology. Key technologies, research and development of independent knowledge and equipment, research and development of typical industry-wide solutions, and the promotion of exercise prescriptions, prevention and control of chronic diseases as a major livelihood needs, Hefei Research Institute of Chinese Academy of Sciences and General Hospital of PLA (301 Hospital) and other units to organize medicine, exercise physiology and Interdisciplinary teams, such as information, started from the methodology to create a sports promotion health technology system, broke key technologies, developed independent intellectual property equipment, and established a sustainable business model through demonstration applications. Based on the results of the project, the People's Liberation Army 301 Hospital opened the nation's first chronic disease treatment clinic, established a clinical pathway for the rehabilitation of chronic disease, and managed 3,600 cases of hypertension, diabetes, and obesity, with an effective rate of over 90%. The technology and management methods were equipped to build 42 community health promotion and scientific fitness guidance demonstration and application bases in more than ten provinces and cities such as Beijing, Tianjin, Guangdong, Jiangsu, Zhejiang and Anhui, and served more than 300,000 people. The established public sports normal operation model was established. It was promoted by Anhui Provincial Sports Bureau throughout the province. Sample statistics show that 90% of the core knowledge of chronic disease patients and 88% of scientific fitness knowledge rate are served by clients, and 67% of the clients have improved their lifestyle.

The “Power Grid Greenhouse Gas (SF6) Leakage Spectrum Remote Sensing Intelligent Online Inspection Technology” project team has comprehensively used high-performance and high-sensitivity Fourier infrared spectrum telemetering technology and robot inspection technology to perform automatic on-line monitoring of SF6 gas leakage, at home It is the first time outside. The main innovations of the project are as follows: A fingerprint-free spectral feature recognition algorithm model for SF6 gas was creatively established, and the high-precision and rapid identification and alarm of SF6 gas on a mobile platform under a complex outdoor environment was realized; a set of substations was established. The inspection scheme and leak detection algorithm model solved the contradiction between inspection speed and detection sensitivity, realized rapid high-sensitivity inspection of substations, and developed a scanning imaging system, which combines high-sensitivity detection technologies and large-scale detection technologies. The combination of SF6 gas leaks enables remote detection, visual search and precise positioning of leaks. The project results were piloted at several substations in Wuhu, Fuyang and Hefei. The SF6 gas leak detection intelligent inspection device was reliable, stable, and well-operated during the grid connection, and it successfully found a leak at the tip of the 110kV Ruidian antenna 533 switch air chamber at the Tianmenshan substation. To avoid a bigger failure of the equipment.
