一、引言任何基于气体分子电离的真空规的灵敏度很大程度上取决于气体的性质。然而众所周知,给定气体的相对灵敏度 R 对标准气体的绝对灵敏度而言看来与规管外形、工作条件等无关。这个事实对推断规管对其它气体的灵敏度是有很大意义的。自从Found 和 Dushman 起,一些研究人员就相继报导了电离规的相对灵敏度。他们注意到,R 值对分子中的电子数目给出的曲线得出近似于直线关系。在我们的研究中,用流导法对包括碳氢化合物在内
I. INTRODUCTION The sensitivity of any vacuum gauge based on ionization of gas molecules depends very much on the nature of the gas. However, it is well-known that the relative sensitivity of a given gas, R, to the absolute sensitivity of the standard gas does not appear to be related to regulatory shape, working conditions, etc. This fact is of great significance to infer the sensitivity to regulate other gases. Since Found and Dushman, some researchers have reported the relative sensitivity of ionization gauges one after another. They noticed that the curve given by the R value for the number of electrons in the molecule gave a near straight line relationship. In our study, the guidance method was used to include hydrocarbons
