电子技术是当代的先导技术。电子工业的发展对我国的四个现代化建设起着支柱作用。真空电子技术是电子技术中一个重要组成部分,自二十世纪初起,真空电子科学技术的发展推动了整个电子科学技术的迅速发展和广泛应用。尽管后来人们充分研究了固体中束缚电子的行为规律,出现了固体电子学,当今半导体电子学、微电子学的深入研究和发展,并以此开发的各种元器件和应用,成为新技术革命和促进社会物质文化生活的主要动力。可是我们决不能忽视真空电子学中有待探索的新规律、新原理、新概念,决不能忽视真空电子科学技 Electronic technology is the contemporary leader. The development of the electronics industry plays a pillar role in our four modernizations. Since the beginning of the twentieth century, the development of vacuum electronic science and technology has promoted the rapid development and widespread application of the entire electronic science and technology. Although later people fully studied the behavior of bound electrons in solids, the emergence of solid-state electronics, semiconductor electronics, microelectronics, in-depth research and development, and thus the development of various components and applications, a new technology revolution And promote the material and cultural life of the main driving force. But we must not ignore the vacuum electronics to be explored new laws, new principles, new concepts, must not ignore the vacuum electron science and technology
