电子技术是无线电技术和电子学两门有密切关系的学科的总称(它们也常常被合称为无线电电子学或简称为电子学)。它是20世纪中发展最迅速的技术科学之一。人们常常把它与原子能和火箭技术井列为现代几个主要的尖端技术。它们对于国民经济和国防建设都有重大的作用。但是从应用的广泛性来说,电子技术是其他尖端技术所难以比拟的。它可以普逼地使生产和科学实验的效率提高。对我国来说,它是促进四个现代化的一个重要技术基础。科学技术的发展决定于人类社会生产斗争和阶级斗争的需要。无线电的发明是由于人类对于改进通信方法有迫切的要求。通信就是讯息传递。在有线电报和电话以前,除 Electronic technology is the general term for two disciplines closely related to radio technology and electronics (they are often collectively referred to as radio electronics or simply electronics). It is one of the fastest growing technical sciences of the 20th century. It is often listed as one of the leading modern technologies with atomic and rocket technologies. They all play a significant role in both national economy and national defense construction. But from the wide range of applications, electronic technology is unmatched by other cutting-edge technologies. It can be used to make production and scientific experiments more efficient. For our country, it is an important technological basis for promoting the four modernizations. The development of science and technology is determined by the needs of the productive and class struggle in human society. The invention of radio was due to the urgent need of humankind to improve communication methods. Communication is messaging. Before the wire and telephone, except
