对低压下探针正离子饱和区的理论进行了修正，使之考虑鞘层边缘的定向电流。该漂移电流解释了电子饱和探针电流与正离子饱和探针电流的理论比与实验比之间的差异。通过使用微波方法来检查理论，以获得离子密度的独立测量。探针和微波测量进行了比较，在0.05-6毫米汞柱的氢气，氩气和氦气的压力区域。
The theory of the positive ion saturation region of probes at low pressure is modified to take into account the directed current at the sheath edge. This drift current explains the discrepancy between the theoretical and experimental ratio of the electron saturation probe current to the positive ion saturation probe current. The theory is checked by using microwave methods to obtain an independent measurement of the ion density. Probe and microwave measurements are compared in the pressure region of 0.05-6 mm Hg in hydrogen, argon, and helium.
