新型膨胀法测压装置

A NEW KIND OF DEVICE OF TESTING PRESSURE WITH EXPANSION METHOD

从静态膨胀法的工作原理出发,指出原膨胀法测压装置存在的问题,对一些主要部件进行重新设计,提出前级标准压力测定新方法。

This paper from the working principle of static expansion method,pointed out the exist problem of the original device, redesigned the major parts and put forward a new way to test the preceding standard pressure.
