摘要
简述了取样式低频电容法测量持水率的基本原理；分析了传感器所测电容的组成，并从理论上详细分析了油膜沾污对持水率测量影响的机理，提出了改进办法。实验证明该方法效果良好。
Discusses the fundamental principles of using sampling type low frequency capacitance method for waterholdup measurement; Analyzes the constituent of the measured capacitance from the sensor as well as the effect of oil membrane on the surface of the electrode on waterholdup measurement, and proposes specific measures for improving waterholdup measurements. The result of those measures is confirmed to be good by experiments.
