PHI595扫描俄歇谱仪是我所从美国引进的大型表面分析仪器。本文结合表面分析技术的发展，对该仪器的PDP-11／04计算机数据处理系统进行了改造，设计了专用的通信接口，将PDP小型计算机与PC／486微机相联接，从而使实验数据能传输入微机中进行运算处理，进一步对俄歇谱所包含的化学态信息作深入研究。
The PHI595 scanning Auger spectrometer is a large surface analysis instrument that I imported from the United States. In this paper, the PDP-11/04 computer data processing system is modified based on the development of surface analysis technology. A dedicated communication interface is designed to connect the PDP mini-computer with the PC / 486 microcomputer so that the experimental data can be passed Enter the microcomputer to carry on operation processing, further make further research to the chemical state information contained in the Auger spectrum.
