在1947年发明了晶体管,1959年发明了集成电路(IC),在1971年又发明了微处理机。看来,在电子工程中发生划时代进步的周期大约是12年。那末下一个重大发展将是什么呢?很多工程师预言它将是所谓月片——就是不需要几个月或几年而只需要31天
The transistor was invented in 1947, the integrated circuit (IC) was invented in 1959, and the microprocessor was invented in 1971. It seems that the epoch-making progress in electronic engineering takes about 12 years. What will happen next major development? Many engineers predict that it will be the so-called lunar - that does not take months or years and only 31 days
