60年代以来,由于固体制造技术的发展,在某一领域使固态技术代替了真空技术。当时认为半导体作为电子媒介优于真空。但是,现在可以认为这是一种错觉。事实上,真空器件处理信息的固有速度比固体器件要快。固体器件的明显优点是由于电路集成,很多小器件封装在一起。 Since the 1960s, due to the development of solid state manufacturing technology, solid state technology has replaced vacuum technology in one area. At that time, semiconductor was regarded as superior to vacuum as electronic media. However, it can now be considered as an illusion. In fact, vacuum devices process information faster than solid devices. The obvious advantage of solid-state devices is that because of circuit integration, many small devices are packaged together.
