引言在任何科学工作中,准确的计量总是十分重要的,真空技术中的低压强测定问题当然也不例外。在所有的真空工作中,都要求有一个量具能可靠地探知工作容器内的压强值(至少是近似的压强值)以便判别在这种真空条件下能否进行我们所要求的一些工作。除此以外,真空的测量还广泛地用于检定真空材料的性 Introduction In any scientific work, accurate measurement is always very important, of course, the problem of low pressure determination in vacuum technology is no exception. In all vacuum work, there is a need for a gauge to reliably ascertain pressure values ​​(at least approximate pressure values) within the working container in order to determine if such work can be performed under such vacuum conditions. In addition, the vacuum measurement is also widely used to test the nature of the vacuum material
