5. China's first sea area gas hydrate test mining
On May 18, 2017, China achieved the first successful trial of flammable ice in the sea. The natural gas hydrate (also known as combustible ice) in the Shenhu area of the South China Sea achieved continuous gas production for 187 hours. This is the outstanding achievement of the "Chinese theory", "Chinese technology" and "Chinese equipment". The Chinese people have climbed to the new peak of world science and technology. The continuous flow of natural gas has been extracted from the ground floor of more than 200 meters below the deep seabed of more than 1,200 meters, igniting the fire-breathing device of the world's largest offshore drilling platform "Blue Whale One". This is the first time in China, and it is also the first time in the world to successfully achieve trial mining of flammable ice in muddy silty reservoirs with more than 90% of resources and the most difficult development. The flammable ice test started from the "Blue Whale No. 1" is not only important for China's future energy security and optimization of energy structure, but may even bring changes to the world's energy replacement research and development pattern.
6. China's "artificial sun" device creates a new world record
National Great Scientific Device - Full Superconducting Tokamak Nuclear Fusion Experimental Device Eastern Super Ring (EAST) has achieved a new world record with a stable 101.2 second steady-state long pulse high-constrained plasma operation. This important breakthrough marks that China's magnetic confinement fusion research will continue to lead the international frontier in the physical and engineering aspects of steady-state operation. The Oriental Super Ring is the world's first tokamak nuclear fusion experimental device to achieve steady-state high-constraint mode operation with a duration of 100 seconds. It has great scientific significance for the International Thermonuclear Fusion Test Reactor (ITER) program. Since the reaction principle of nuclear fusion is similar to that of the sun, the Oriental Super Ring is also called the "artificial sun." This achievement will provide important scientific and experimental support for the future ITER long pulse high-constraint operation, 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.
7. Chinese scientists first discovered a breakthrough in traditional classification of new fermions
For the first time, the research team of the Institute of Physics of the Chinese Academy of Sciences discovered a new type of fermion, the triple degenerate fermion, which broke through the traditional classification, which opened up a new direction for the study of electronic topological states in solid materials. The research results were published online by Nature on June 19, 2017. The search for a new type of fermion is a challenging frontier scientific issue in the field of topological state in recent years, and it is also one of the focuses of international competition in this field. The discovery of the new Fermion from the theoretical prediction, sample preparation to the experimental observation process is independently completed by Chinese scientists. It is an important breakthrough in solid theory in condensed matter physics. This research has important implications for promoting people's understanding of electronic topological states, discovering novel physical phenomena, developing new electronic devices, and understanding the properties of elementary particles.
