摘　　要：本文采用溶剂萃取法、加热汽化法和解吸色谱法对XLPE、PP和PET中的含水量进行了测定,系统地介绍了各种方法的实验条件和影响因素,对比了各方法的优越性及其测定结果,对实验现象进行了解析,为测定聚合物的含水量提供了理论依据和参考数据。This paper deals with the determination of moisture content in polymeric dielectrics with three different methods, e. g. solvent extraction method, heat evaporating met- hod and desorption chromatographic method for three different materials such as XLPE, PP and PET The experiment procedure and various factors which affect the accuracy were described. The merit of each method and the results obtained from experiment determination were discussed.
