摘要：
Under humidity step changes, the measured ac-dc difference results from a thermal converter and a range resistor at 200 V in the frequency range from 40 Hz to 100 kHz have shown that a first order differential equation can be used to model the behaviour. The humidity coefficients for the model are found to be strongly frequency-dependent and the time constants are related to the changes of the humidity.
