提出了一种利用空心阴极型放电管测量电子温度的浮动探针方法。当交流电压通过中间阻断电容器施加到探针上时，所提出的方法检测浮动电位的移位。浮动电位的位移被描述为电子温度和施加的交流电压的函数。浮动探针法比朗缪尔探针法简单，因为它不需要测量伏安特性。随着输入交流电压的增加，电子温度收敛。在施加正弦电压的情况下，用浮动探针法测得的电子温度在浮动电位范围内接近第一（尾）电子温度。
This study presents a novel floating probe method to measure electron temperatures using a hollow cathode-type discharge tube. The proposed method detects a shift in the floating potential when an AC voltage is applied to a probe through an intermediary blocking capacitor. The shift in the floating potential is described as a function of the electron temperature and the applied AC voltage. The floating probe method is simpler than the Langmuir probe method because it does not require the measurement of volt-ampere characteristics. As the input AC voltage increases, the electron temperature converges. The electron temperature measured using the floating probe method with an applied sinusoidal voltage shows a value close to the first (tail) electron temperature in the range of the floating potential.
