摘　　要：对聚乙烯毗咯啉酮悬浮液在２０号变压器油中组成的电流变液进行了研究，推导了ＥＲ流体屈服应力ｒｙｅ的理论计算公式得出其屈服应力与基础液的介电常数εｆ、外加电压Ｕ和分散质的含量的百分比的函数关系，这种关系在实验中得以证实．This paper deals with the properties of electrorheologicai liquids composed of polywinylpyrrolidone suspension and transformer oil. The theoretical caculation formula of yield stress τye is presented.The function relation among yield stress, permittivity of disper-santsξextraneous electrical voltage U and volume fraction of dispersed phase are also ob-tained. The theoritical results agree with the experimental data.
