| 摘 要： | 电流变体作为智能材料作动器的一种，在外加电场的作用下，其材料性能会发生显著的变化。本文主要研究了二氧化硅／淀粉复合颗粒电流变体在交变电场作用下的透光性能的变化。对不同浓度的流体、不同外加电场强度，不同外加电场频率以及不同电极间距几种情况下电流以变体的透光性均进行了测试。

| Abstract: | The material properties of electrorheological fluid can be changed markedly while an external electric field is imposed on ER fluid domain.In this paper,the laser transmissivity of an ER suspension of silica/starch composite particles is investigated.An alternating electric field is utilized.The transmission under different situations such as various concentrations of ER fluid,various electric field strengths and frequencies and various distances between two electrodes are measured. |
