The scientific instrument, China-EAST, the fully superconducting tokamak nuclear fusion experimental device, has realized the stable operation of 10 1.2 second steady-state long pulse high confinement plasma, creating a new world record. This important breakthrough indicates that China's magnetic confinement fusion research will continue to lead the international frontier in the physical and engineering aspects of steady-state operation.

Oriental Hyperloop is the world's first tokamak nuclear fusion experimental device, which can run 100 second in steady-state high constraint mode. This is of great scientific significance to ITER project. Because the reaction principle of nuclear fusion is similar to that of the sun, the Oriental Hyperring is also called "artificial sun".

This achievement will provide important scientific and experimental support for ITER's long pulse and high constraint operation in the future, and also lay a foundation for the pre-research, construction, operation and personnel training of China's next generation fusion device, China Fusion Engineering Experimental Reactor.

2. The domestic water glider dived 6329 meters underwater, setting a new world record.

On March 20 17, the "Haiyi" water glider independently developed by China completed the deep dive observation mission in the Challenger Abyss of Mariana Trench and recovered it safely. The maximum dive depth reached 6329 meters, setting a new world record for the maximum dive depth of water gliders.

"Haiyi" water glider is a new underwater observation platform with completely independent intellectual property rights developed by Shenyang Institute of Automation, China Academy of Sciences according to the deployment of Class B strategic pilot project of Chinese Academy of Sciences.

It took 13 years from the prototype development to the successful completion of the abyss observation mission, including more than 20 underwater gliders of different types such as shallow sea, deep sea and abyss.

This time, "Haiyi" completed 12 dives in the Mariana Trench, with a total voyage exceeding 134.6 km, and collected a large number of high-resolution water information in the abyss, which provided valuable information for marine scientists to study the hydrological characteristics of this area.

3. The world's first optical quantum computer was born, which surpassed the early classical computers.

On May 3rd, 20 17, the scientific research team of Academician Pan Jianwei of China University of Science and Technology announced that the optical quantum computer was successfully built. Pan Jianwei team has always maintained the international leading level in the field of multiphoton entanglement. The team used the self-developed quantum dot single photon source with the best comprehensive performance in the world to construct the optical quantum computing prototype of multi-photon "Bose sampling" task through electronically controlled programmable optical quantum circuits.

The experimental test shows that the sampling speed of the prototype is at least 24,000 times faster than the similar experiments of international counterparts, and it is also 10 to 100 times faster than the first electron tube computer and the first transistor computer in human history.

This optical quantum computer marks a breakthrough in the research of photon-based quantum computer in China, and lays a solid foundation for the ultimate realization of quantum computing beyond classical computing power.

4. The domestic large passenger plane C9 19 made its first flight.

China's first international mainstream domestic large passenger plane C9 19 made its first flight at Shanghai Pudong International Airport on May 5/July 20 14. The full name of C9 19 is "COMAC9 19", and COMAC is the abbreviation of China Commercial Aircraft Corporation, the main manufacturer of C9 19.

"C" is not only the initials of "COMAC", but also the initials of CHINA's English name "China", which shows that a large passenger plane is the will of the country and the expectation of the people. The first 9 means "forever", and 19 means C9 19. The maximum passenger capacity of a large passenger plane is 190.

C9 19, with completely independent intellectual property rights, is a landmark project for building an innovative country, which has condensed the best design talents and engineering talents in China. According to the advanced aerodynamic layout, structural materials and airborne system, the developer has planned 102 key technical breakthroughs, including the integrated design of aircraft engine, the control law design of fly-by-wire flight control system and active control technology.

5. The first trial exploitation of natural gas hydrate in China sea area.

On May 8, 20 17, China successfully tried to mine combustible ice in this sea area for the first time, and the natural gas hydrate (also known as combustible ice) in Shenhu sea area of South China Sea achieved a stable production in 187 hours. This is an outstanding achievement of China Theory, China technology and China equipment, and the people of China have reached a new peak in world science and technology.

A steady stream of natural gas was mined from the seabed more than 200 meters below 1.200 meters, which ignited the flamethrower of the world's largest offshore drilling platform "Blue Whale No.1". This is the first time in China, and it is also the first time in the world to successfully test and produce combustible ice in argillaceous siltstone reservoir with resources accounting for more than 90% and the most difficult development.

The trial exploitation of combustible ice by "Blue Whale No.1" is not only of great significance to China's future energy security and energy structure optimization, but may even bring changes to the world energy substitution research and development pattern.
