摘要：

Preliminary results of AC-DC difference measurements using a thermal voltage converter with range resistor. under humidity change conditions are reported. The AC-DC difference measurement results, from a Holt-11 thermal converter at 100 and 200 V and frequency range from 40Hz to 100kHz, have shown that a first-order differential equation can be used to model this phenomenon. The humidity coefficients for the model are found to be frequency dependent and the time constants are related to the changes of humidity.
