| 摘 要： | 在低频范围内（１００ｋＨｚ之内）自来水和地层水都是电的良导体。由此出发可以推论：在低流速下取样式电容含水率诗的主要测量误差来自于油对内电极的沾污，实验证实了这一结论。本文对沾污导致的误差进行了定量分析，并提出了传感器电极的设计原则。

| Abstract: | In low frequency range (within 100kHz), both tap-water used for calibrationand formation water are good electric conductors. Based on this fact, it is predictedthat the output drift of the sample type capacitance water cut meter is caused by inside electrode being contaminated with oil. The prediction has been proved by experiment. In present work, the error caused by oil contamination is analysed quantitatively. The design principle for the sensor is also proposed. |
