在环顾无綫电电子学科学技术方面多种多样的成就的时候,現在完全可以有根据地說,1859年伟大的俄罗斯科学家兼发明家A.C.波波夫关于可以不用导线(即用无綫电波)能够传输訊号的发明是科学技术发展中新紀元的开端。在此以前,电磁波被认为只不过是一个物理学的概念。那时还沒有发現它可貴的性貭,而現在这些性貭的利用已經在无綫电通訊、广播、电视、无綫电导航、射电頻譜学、射电天文学等部門中获得了許多輝煌的成就。只是由于电真空器件的广泛应用才有可能掌握无
In looking into the diverse achievements of radio-electronic science and technology, it is now perfectly well established that the great Russian scientist and inventor AC Popov in 1859 was able to claim that radio waves can be used without wires The invention of transmitting signals is the beginning of a new era in the development of science and technology. Until now, electromagnetic waves were considered as just a concept of physics. At that time, no valuable humanity was discovered yet, and the use of these sexual resources has now gained many brilliant achievements in such sectors as radio communications, broadcasting, television, radio navigation, radio-frequency spectroscopy and radio astronomy . Only because of the widespread use of electrical vacuum devices is it possible to master nothing
