High-tech category
Remote sensing technology: this is a comprehensive detection technology developed vigorously in the 1960 s. It perceives the image of moving matter from a distance, records the electromagnetic wave signals radiated (or reflected) by distant objects with the help of special optical, electronic and electro-optical detection instruments, and then processes the images that can be directly recognized by adult eyes, thus revealing the properties and changing laws of the detected objects.
Superconducting technology: a technology that uses the unique properties of superconducting materials for scientific research and practical application, which is called superconducting technology.
Microelectronics technology: the application of electronic technology 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. Microelectronics technology is the miniaturization development technology of electronic technology.
Microwave communication: Microwave usually refers to electromagnetic waves with a wavelength of 0.3m to 10-3m and a frequency of 109 Hz to 3x1-11Hz. Using the characteristics of microwave, an antenna system with small volume and strong directivity can be made for long-distance communication. Microwave can pass through the ionosphere without obstacles, and the communication quality is much higher than that of short wave, which provides a broad prospect for the research and development of cosmic communication, navigation, positioning and radio astronomy.
Ultrasonic technology: Ultrasonic wave refers to vibration wave whose frequency exceeds the audio frequency range. Ultrasonic technology has become a special field to study the application of ultrasonic in production technology and related measurement technology and instruments and equipment. Defects in materials can be detected by using the change of ultrasonic propagation speed in gases, liquids and solids. When used for detection, it can be seen more clearly and deeply, except for the radiation hazard caused by X-ray detection.
Artificial intelligence: it is a science and technology that uses computers to simulate human intelligence activities. Its research results are mainly reflected in the progress of electronic computers and robots.
Multidimensional space technology
Multidimensional space technology, its basic point is that space is multidimensional. Bakhard Heim, a German physicist, suggested that if there were more dimensions in the universe, spacecraft could travel in them and achieve the ultimate speed.
