Ten major milestone events of China's scientific and technological innovation in 2017
time2018/01/03
1, "Mo-tse" successfully achieved the goal
In June 16, 2017, the joint Academy of Chinese Academy of Sciences, headed by academician Pan Jianwei, published the paper in science. It announced that the "Mo-tse" quantum satellite successfully achieved the kilometer level two way quantum entanglement distribution and the large-scale quantum nonlocality test. In August 10th, two scientific papers on quantum Pan Jianwei team satellite "Mo-tse" also published online in the international journal "nature" authoritative academic journal, the contents are "Mo-tse" for the first time in the world successfully distributed from the satellite to the ground quantum key, and from ground to satellite quantum teleportation.
2, "Tian Zhou 1" completed a number of applications
In April 20, 2017, the first cargo ship "China day boat one launch, and then" Tiangong two "space laboratory successfully completed the first automatic rendezvous and docking. After the completion of the docking, "Tian Zhou 1" enters the setting of the assembly body. In April 27th, "Tian Zhou Hao" cargo spacecraft and "Tiangong No. two" space laboratory successfully completed the first propellant on orbit supplementary test, marking the "Tian Zhou I" flight mission has been successful. In June 19th, "Tian Zhou one" and "Tian Gong two" completed the second rendezvous and docking tests. The successful completion of this test has consolidated the multi-directional space rendezvous technology of the spacecraft, which is of great significance for the construction of the follow-up space station.
3. "Wukong" discovered anomalous electronic signals
In November 27, 2017, the dark matter particle detection satellite "monkey" flight more than 700 days later, the dark matter satellite team announced: "monkey" won the TeV most accurate international cosmic ray electron energy spectrum, and the first direct measurement of the energy spectrum at 1TeV (1 trillion EV) at the turn. The trace of the suspected dark matter is a major discovery in recent years by scientists from the dark matter, which will open a new window on the human observation of the universe. The positive and negative electron pairs produced during the annihilation of dark matter in the universe may produce some special signals in the total energy spectrum of the electronic cosmic rays. Wukong, as the most high-energy particle detection satellite in the world, has the most widely observed energy segment, the best energy resolution and the ability of particle identification, and capturing these signals is the primary scientific goal.
4, the success of C919 first flight of large domestic aircraft
In May 5, 2017, China's domestic C919 airliner was successfully flying at Shanghai Pudong International Airport.
C919 large passenger aircraft design is located in the most mainstream of the air transport market 150 level single channel market, the standard range of 4075 kilometers, increase the range of 5555 kilometers. Since its development in July 2008, the designers of C919 have stepped out of the development path of "Chinese design, system integration, global bidding and gradually upgrading localization", and adhere to the technological line of "independent development, international cooperation and international standards".
The researchers have planned 102 key technologies, 22 provinces and cities in China, and hundreds of thousands of industrial personnel to participate in the research and development. C919 has promoted the progress of China's industrial technology and promoted the revolution in the field of industrial materials.
5, combustible ice production achieved a major breakthrough
Natural gas hydrate (flammable ice) is an ice like crystalline substance distributed in deep sea sediments or in the permafrost of land domain. After burning, it produces only a small amount of carbon dioxide and water, which is 10 times higher than coal, oil and natural gas.
6. The main project of the Hong Kong Zhuhai Macao Bridge
In July 7, 2017, the harbour Zhuhai Macao Bridge undersea tunnel was formally connected. This means that the world's longest trans sea bridge, the Hong Kong Zhuhai Macao Bridge, has realized the full line of the main project. After opening the car, the car ride between Zhuhai, Macao and Hongkong will be shortened from 3 hours to half an hour.
7. The opening of the quantum secure communication trunk line
In September 29, 2017, the world's first quantum secret communication trunk line "Beijing Shanghai trunk line" was officially opened. The "Beijing Shanghai trunk line" and the "Mo-tse" quantum scientific experiment satellite have successfully butted successfully, and the intercontinental quantum secure communication has been realized for the first time. This means a solid step in the future of quantum secure communications covering the world.
8, a stone star launch Beidou No. three
In November 5, 2017, China successfully launched two Beidou three global networking satellites at the Xichang satellite launch center with the long march No. three carrier rocket. After the launch of the satellite, the related test and network verification will be carried out, and the service will be carried out at the right time. The positioning accuracy after the completion of the three Beidou global navigation system will increase 1 to 2 times, up to 2.5 meters to 5 meters, will provide users with free services, civil position about 10 meters accuracy of 0.2 M / sec speed service, and will provide higher levels of precision to paying customers.
9, "revival" named and put into operation
In June 25, 2017, the Chinese standard EMU with fully independent intellectual property rights and the world's advanced level was officially named "Fuxing" and was officially launched in Beijing-Shanghai high-speed railway in June 26th.
10, "the island" artifact "day Kun".
In November 3, 2017, the biggest Asian cutter of our own design and build the dredger "Kun" was launched in Jiangsu in Qidong.
"Kun" equipped with a maximum power delivery system of mining system, Asia's most powerful and automatic control system of the current international most advanced. Its pump power is 17 thousand kilowatts, the highest power allocation in the world, and its long-distance transport capacity of 15 thousand meters, the world's most.
