近几年来,半导体器件在仪器仪表上的应用有了很大的发展,尤其是大规模集成电路的应用,使新型号仪器具有精度高、体积小、耗能少、寿命长等特点。某些还带有数字显示、自动记录、自动打印和数据处理机等装置。致使很多老型号仪器处于淘汰或即将淘汰的更新换代过程中。但在另一方 In recent years, the application of semiconductor devices in instrumentation has made great progress, especially the application of large-scale integrated circuits, so that the new type of instruments with high precision, small size, low energy consumption, long life and so on. Some also come with digital display, automatic recording, automatic printing and data processing devices. As a result, many older models are in the process of being eliminated or about to be eliminated. But on the other side
