真空系统的压强—时间曲线诊断法

Diagnosis to Vacuum System with Pressure Time Curve

应用真空系统的静态压强与时间的 Ｐ－Ｔ曲线，可以诊断出真空系统存在的问题：漏气、放气和蒸汽源，这为真空设备的调试和运行提供了简便和实用的诊断手段。

It is possible to diagnose problems: leakage, desorption and vapour source in vacuum system, with its statical pressure time curve. In order to adju- st and operate a vacuum appratus, it is a simple and practical diagnostic method.
