摘要:
电流变液是一种极有发展前景的新颖材料，通常由不导电的母液和均匀散布在其中的电介质微粒组成。对于外加电场的变化，它的力学性能可以作出迅速的响应，因而在工业上极具应用前景。本文将就电流变液的研究进行综述，涉及的内容有：电流变效应的机理、电流变液材料及其力学性能、应用和展望．
Abstract:Electrorhcological(ER) fluid is a kind of new promising material.Usually,it consists of a suspension of fine dieleclric particles in a non-conduc-tive base liquid,Its mechanical ch‘1racterislics change rapidly in the prescnce of an applied clectric field,This phenomenon has potential applications in industries and technologics,In the present paper,the studies on ER fluids are reviewed including its physical mechanism mechanical characteristics,materials technology,application and prospects.
