引言在10~(-4)毫米汞柱以下的低氣压的测量工作上,利用电离规是通常最方便的方法,但是不容易得到准确结果。特别因为往往存在氣体的清除和交换的现象。在测量的过程中,点燃燈丝、电离、放电与个体表面状态都能起改变真空度的作用。H.Schwarz利用分子氣压表、麦氏规及电离规的同时测量,在氢、氮和氩氣中研究了电离规测量时的特殊现象。Bloomer与Haine研究电离规测量量的氣体清
Introduction Ionization gauges are generally the most convenient method of measuring atmospheric pressure below 10-4 mm Hg, but accurate results are not readily available. Especially since there is often the phenomenon of gas removal and exchange. In the measurement process, ignite the filament, ionization, discharge and the individual surface state can play a role in changing the degree of vacuum. H. Schwarz uses the simultaneous measurement of molecular barometers, Wheat’s gauge and ionization gauge to study the special phenomena of ionization gauge measurements in hydrogen, nitrogen and argon. Bloomer and Haine study ionization gauges for gas clarity
