1, China's "artificial sun" device set a new world record
National large scientific device - all-superconducting tokamak fusion experimental device Oriental Ultra Ring (EAST) achieved a stable 101.2-second steady-state long-pulse high confinement plasma operation, setting a new world record. This important breakthrough signifies that China's magnetic confinement fusion research will continue to lead the international frontier in the physics and engineering of steady-state operation.
Dongfang Super Ring is the world's first experimental tokamak fusion device to achieve steady-state high confinement mode operation duration of the order of a hundred seconds, which is of great scientific significance to the International Thermonuclear Experimental Reactor (ITER) program. Because the reaction principle of nuclear fusion is similar to that of the sun, the Oriental Super Ring is also known as the "artificial sun".
This achievement will provide important scientific and experimental support for the future ITER long-pulse, high-confinement operation, and also lays the foundation for the pre-study, construction, operation and talent training of China's next-generation fusion device, the China Fusion Engineering Experimental Reactor (CFER).
2, China's underwater glider dives 6329 meters to set a new world record
China's independently developed "Sea Wing" underwater glider in the Marianas Trench Challenger Deep in March 2017, to complete the observation of large-depth dive mission and safely recovered, the maximum depth of 6329 meters, a new record of 6329 meters, the maximum depth of 6329 meters. It set a new world record for the maximum dive depth of an underwater glider.
The "Sea Wing" underwater glider is a new underwater observation platform with completely independent intellectual property rights developed by the Shenyang Institute of Automation of the Chinese Academy of Sciences according to the deployment of the Class B Strategic Pilot Project of the Chinese Academy of Sciences.
From the research and development of the principle prototype to the successful completion of the abyssal observation mission has experienced 13 years, including shallow sea, deep sea, abyssal and other different types of underwater gliders more than 20 units.
The "Sea Wing" completed 12 dives in the Marianas Trench***, with a total range of more than 134.6 kilometers, and collected a large amount of high-resolution information on the water in the abyssal region, which provides valuable information for marine scientists to study the hydrological characteristics of the region.
3, the world's first beyond the early classical computer of the birth of optical quantum computer
May 3, 2017 University of Science and Technology of China, academician Pan Jianwei scientific research team announced the successful construction of optical quantum computer. Pan Jianwei team in the field of multi-photon entanglement has always maintained the international leading level, the team used the independent development of the comprehensive performance of the international best quantum dots single-photon source, through the electronically programmable optical quantum line, constructed for the multi-photon "boson sampling" task of the optical quantum computing prototype.
Experimental tests show that the prototype's sampling speed is at least 24,000 times faster than that of similar experiments by international peers, and by comparing it with classical algorithms, it is also 10 to 100 times faster than that of the first electron-tube computers and the first transistorized computers in the history of mankind.
This optical quantum computer marks a breakthrough in China's research on photon-based quantum computers, laying a solid foundation for the eventual realization of quantum computing beyond classical computing capabilities.
4, domestic large passenger aircraft C919 first flight
China's first international mainstream level of domestic large passenger aircraft C919 on May 5, 2017 at 14:00 in Shanghai Pudong International Airport, the full name of the C919 is "COMAC919", COMAC is the C919 main manufacturer COMAC, the English name of the C919 manufacturer COMAC. COMAC is the abbreviated English name of COMAC, the main manufacturer of the C919.
The "C" is the first letter of "COMAC" as well as the first letter of China's English name "CHINA", reflecting the fact that the large passenger airplane is the will of the country and the expectation of the people. The first 9 symbolizes "the will of the country and the expectation of the people". The first 9 means "long life", and 19 means that the C919 large passenger aircraft has a maximum capacity of 190 people.
The C919 has completely independent intellectual property rights, is a landmark project to build an innovative country, cohesion of the country's best design talent and engineering talent, for the advanced aerodynamic layout, structural materials and airborne systems, the developers **** planning 102 key technology research, including the aircraft engine integration design, fly-by-wire flight control system control law design, active control technology and so on.
5, China's first sea gas hydrate test mining
May 18, 2017, China's first successful sea combustible ice test mining, the South China Sea God Fox sea natural gas hydrate (also known as combustible ice) test mining to achieve a continuous 187 hours of stable gas production. This is "China's theory" "China's technology" "China's equipment" condensed into an outstanding achievement, the Chinese people have climbed to a new peak of the world's science and technology.
A steady stream of natural gas was extracted from a bottom layer more than 200 meters below the 1,200-meter-deep seabed, igniting the flamethrower of the world's largest offshore drilling platform, the Blue Whale I. This is the first time in China, and the first time in the world, that this has been done. This is the first time in China, and the first time in the world to successfully realize test mining of combustible ice in muddy silt-type reservoirs, which accounts for more than 90% of the resources and is the most difficult to develop.
From the "Blue Whale I" started combustible ice test mining, not only for China's future energy security, optimization of energy structure is of great significance, and may even bring a change to the world's energy succession research and development pattern.
