摘    要：研究了重油中水分检测的新方法.基于水的介电常数远远大于重油的介电常数,因而两者所呈现的射频阻抗特性不同.作者采用射频传感器和专门的测量系统进行A/D转换、非线性校正、数据处理,从而可以快速地测量出重油中的含水率.

Abstract: The dielectric constant of water is far greater than that of heavy oil,and so they show different specific properties in the respect of radiofrequency impedance.The authors sutdy a new method of measuring water content in heavy oil,adopt radiofrequence sensors and use special measuring system to have A/D conversion,non-linear rectificaiton and data processing.As a result,we can very quickly measure the water content in heavy oil.
