油饱和蒸汽压的测试及自动平衡式真空微量天平

Measurement of the Saturation Vapour Pressure of Oil and Auto balanced Vacuum Micro mass Balance

本文叙述了用蒸发率法测定真空及航天用油及油脂饱和蒸汽压的原理和方法。

The principle and the method of measurement of the saturation vapour pressure of oil used in vacuum and space technology by means of the evaporation rate were described in this paper. And also the structure and the principle of the special developped auto balanced vacuum micro mass balance.
