研究了外加电场对在光滑板与高精度钢球之间小间隙中形成的介电液体半月板的影响。结果表明，在低介电常数介质液体的半月板上，薄膜被拉出并移开。在扩散初期，由于液体半月板三相接触线（TCL）附近的气体放电，观察到强烈的“电风”。然而，在经典电润湿研究中常用的导电液体半月板中却没有这种电扩散现象。推导出电场作用下液体半月板的扩散是由TCL附近的热毛细力驱动的。
The effects of an external electric field (EEF) on dielectric liquid menisci formed in a small gap between a smooth plate and a high precision steel ball have been investigated. It was found that thin spreading films were pulled out and moved away from the menisci of low permittivity dielectric liquids after exposure to the EEF. During the initial period of spreading, a strong “electric wind” due to the gas discharge in the vicinity of the three-phase contact line (TCL) of the liquid meniscus was observed. However, such electrospreading phenomena were absent for the menisci of conductive liquids which were commonly used in classical electrowetting studies. It is deduced that the spreading of liquid menisci under EEFs is driven by the thermocapillary force near the TCL.
