摘要
直流电场中电导率的微小变化会影响电流变效应是一个显见的事实，但长期以来，在电流变机理的研究中却被忽略．文章介绍近年来电流变液中的电导率问题研究的若干重要进展，包括经典点偶极子模型在直流电场中的改进。
Although it is known that very small conductivity can influence electrorheological (ER) effects in DC fields, the effect of conductivity was omitted for a long time in the study of the ER mechanism. Recent developments of studies on conductivity effects in ER fluids are briefly reviewed, focussing on the improvement of the classical point dipole model, negative ER effects and the conduction model.
