Biotechnology has achieved unprecedented development in the 20th century, especially the discovery of the double helix structure of DNA and the implementation of the Human Genome Project, which has made biotechnology the mainstream of high-tech in the 21st century. Because biotechnology can reveal the secrets of biological structure and genetics, it plays a significant role in promoting the development of population and health, agricultural high-tech, ecological environment, food and chemical industries and other fields.

2. Space technology

In the past half century, with the development of aerospace technology and the widespread use of various application satellites, mankind has pioneered satellite communications, satellite broadcasting, and satellite meteorology. , satellite navigation, satellite survey and space science, military applications and other unprecedented new fields of space technology development for radio and television, long-distance communications, weather forecast, resource census, navigation and positioning, agricultural production, rescue and disaster relief, environmental monitoring and scientific research.

3. Remote sensing technology

This is a comprehensive detection technology that flourished in the 1960s. It senses the image of moving matter from a distant place. With the help of specialized optical, electronic and electronic optical detection instruments, the electromagnetic wave signals radiated (or reflected) by distant objects are received and recorded, and then processed into images that can be directly recognized by the human eye, thereby revealing the detected objects. properties and changing patterns.

4. Microelectronics technology

Use the basic laws of electronics to study various electronic components, devices, equipment and systems, which are widely used in various fields of national economy, national defense and science and technology. Applied technology is electronic technology. Microelectronics technology is the miniaturization development technology of electronic technology.

5. Microwave communication

Microwave usually refers to electromagnetic waves with wavelengths from 0.3 meters to 10-3 meters and frequencies from 109 Hz to 3x11-11 Hz. Using the properties of microwaves, antenna systems with small size and extremely high directivity can be made for long-distance communication. Microwaves can pass through the ionosphere without any hindrance, and the communication quality is much higher than shortwave, providing broad prospects for the research and development of space communications, navigation, positioning, and radio astronomy.
