【摘要】 利用Ｈｅ－Ｎｅ激光测量ＳｉＯ２和硅油组成的电流变液的透光性。平行于激光束施加电场时，适当浓度的电流变液显示出透光性随电场可调节的特征。垂直于激光束施加电场时，透射光强度迅速下降随后缓慢恢复，但对于高浓度（２％）试样没有观察到透射光强度最初的快速下降阶段。更多还原

【Abstract】 Measurements have been made of He Ne laser transmission through suspensions of SiO 2 in silicone oil. When electrostatic fields were applied paralled to the laser path, transmission could be adjusted through selecting proper electrostatic field and suspension concentration. While electrostatic fields were applied perpendicular to the laser path, transmission declined quikly and then recovered slow, but no initial decline was observed for high concentration suspensions.更多还原
