This set of 2017 stamps shows a number of internationally leading achievements in the field of science and technology:
The first: 500-meter spherical radio telescope.
The main structure of the telescope is displayed, and the three major independent technological innovations of active reflector technology, light cable drag feed support technology and the use of natural landforms to build giant telescopes are depicted.
The background of the stamp demonstrates the powerful functions of the telescope as a multidisciplinary basic research platform by representing scientific symbols such as neutral hydrogen, pulsars, and space celestial bodies.
Observation under ultraviolet light simulates the scientific principle of the radio telescope receiving signals from the sky, and then reflecting from the mirror surface of the radio telescope to the feed source.
The second: "Mozi" quantum science experimental satellite.
The main scientific goal is to use satellite platforms to carry out satellite-to-earth high-speed quantum key distribution experiments, and on this basis to carry out wide-area quantum key network experiments;
And carry out quantum entanglement distribution and quantum teleportation experiments on the space scale, and carry out experimental research on the completeness of quantum mechanics at the space scale.
The stamp uses satellites and the earth in space as the main objects. The five points on the earth represent the four quantum communication ground stations of Nanshan, Delingha, Xinglong, and Lijiang, and the experimental station of quantum teleportation in Ali.
Under ultraviolet light, the two beams of light directly hit the Beijing Xinglong Station and the Xinjiang Nanshan Station, representing the most important scientific experiment of the "Mozi".
The third one: "Exploration One" scientific research ship.
The 4,500-meter manned submersible working mother ship and the deep-sea scientific research general platform-"Discovery One" were displayed. In addition, it also showed the "Haidou" unmanned submersible, "Tianya" lander, The image of the "Haiyi" underwater glider.
Under the ultraviolet light, the "Haidou" unmanned submersible, the "Tianya" lander and the "Haiyi" underwater glider have the largest diving depth on the seabed.
Fourth piece: Bohai Granary Technology Demonstration Project.
The harvest scene is shown, reflecting the significant effects of the transformation of low- and medium-yield fields and saline-alkali wasteland on increasing agricultural production and income. In addition, the new technologies such as drones and field detectors in the stamps also reflect the background of modern agricultural technology. Traditional agricultural technology changes.
Under ultraviolet light, the higher the lower the salt, the lower the salt during the transformation of the saline-alkali land.
Fifth: "Shenwei·Light of Taihu Lake" supercomputer.
The display shows the supercomputer cabinet located in the National Supercomputing Wuxi Center in Jiangsu Province. The background of the screen shows the wide application of supercomputers in national high-tech fields and cutting-edge technology research such as aerospace, weather and climate, biological information, materials science, and computational chemistry.
Under ultraviolet light, the binary "0" and "1" emitted by the computer visualize the invisible super computing power.
