中文摘要：
基于润滑理论和漏介电质模型，通过建立电场作用下非平整基底上液滴铺展的演化模型，利用PEDCOL程序模拟了导电液滴在非平整基底上的铺展特征。结果表明：非平整基底有助于加快液滴的铺展速度，其中，锯齿状基底下液滴的铺展速率最大；底部电势为恒定值时，电场对液滴铺展起抑制作用；线性底部电势将诱导液滴中心出现偏移现象，且液膜轮廓呈现与基底外形相似的特征；增加基底波数或高度，均有利于液滴铺展，但其影响总体较小。
英文摘要：
An evolution model on uneven substrate is established, based on the leaky dielectric model and theory of lubrication, to analyze the spreading of a conductive droplet in the presence of electric field. The PEDCOL pro- gram is applied to the numerical simulation during modelling. Results show that the uneven substrate can accelerate the speed of spreading, and the maximum rate occurs when the droplet spreads on serrated basement. The sprea- ding of droplet is suppressed in the constant electric field. When the electric potential becomes linear, deviation from the droplet centre appears with its spreading profile similar to that of uneven substrate. Increasing the wave number or height of the substrate facilitates the droplet spreading, but the effect is relatively weak.
