摘　　要：本文介绍基于射频阻抗理论对重油的含水量进行快速检测和温度补偿的方法，探讨传感器特性的非线性三维补偿和多参数校正技术在水分检测中的应用，对实验结果进行了误差分析，计算表明最大非线性误差为０．５％。In this paper ,a method to measure water content quickly in heavy oil and of temperature compensation is introduced base on the theory of radiofrequency impedace. Then,we discuss the application of three- dimensional compensation of non-linearity and parameters' rectification in water content test. Finally,error analysis for a group of experiment results is described.
