自本世纪初发明电子管以来,电子技术经历了晶体管、中小规模集成电路(IC),直到今天的超大规模集成电路(VLSI),它最具代表力的芯片——微处理器集成度在几个平方厘米之间已达到2,000多万个晶体管.电于技术的这场革命,使得整个世界的面貌发生了巨大的改变:在外层空间来回穿梭的航天飞机、恢宏悲壮的海湾战争、美观省油的各式轿车、满足视听享受的家用电器及被人们称作千里眼、干里耳的通信设备,都是高速发展的电子技术广泛应用的结果.
Since the invention of electronic tubes at the beginning of this century, electronic technology has gone through transistors, small and medium-scale integrated circuits (ICs), and up to today’s VLSI, its most representative chip—the degree of microprocessor integration in several Between the square centimeters, more than 20 million transistors have been reached. The revolution in technology has brought about a tremendous change in the entire world: space shuttles shuttled back and forth in outer space, the magnificent tragic Gulf War, beautiful fuel-efficient Cars, home appliances satisfying audio-visual enjoyment, and communications equipment that people call clairvoyance and stem-to-ear communication are the result of the widespread application of high-speed development of electronic technology.
