电子技术又叫电子学。起初大都用在无线电通讯上,所以也叫无线电技术。因为发展了半导体和半导体的应用,半导体材料和器件的研究和应用越来越广泛,所以半导体技术在电子技术中占了统治地位,几乎所有现代化技术中都应用它。电子技术是一门研究电子发射和运动规律以及电子器件的创造的科学。电子技术用途很广,好象“药铺里的甘草”,那里都有它一份,所以,它发展最快,应用最广。目前,可以说上至天文(射电天文),下至地质探查,大至宇宙太空,小至核物理研究,从日常生活到 Electronic technology is also called electronics. At first, mostly used in radio communications, so called radio technology. Because of the growing use of semiconductors and semiconductors, research and applications of semiconductor materials and devices are becoming more widespread, semiconductor technology dominates electronics and is used in almost every modern technology. Electronic technology is a science that studies the laws of electron emission and movement and the creation of electronic devices. The use of electronic technology is very wide, as if “medicine shop licorice”, where it has a copy of it, so it is the fastest growing and most widely used. At present, we can say that astronomy (radio astronomy), geological prospecting, large space science, nuclear physics research, from everyday life
