本文计算了在电场作用下，液滴浸入不互溶液体中时，液滴形状的变化。电荷通过欧姆电流通过界面和通过界面上的对流分量转移。分析了以电压力与毛细管压力之比为参数的二次型解。找到了液滴沿着电场方向变为扁长球或椭球的条件，并对液滴在电场作用下的变形进行了实验研究。
The variation of the shape of a drop immersed in an immiscible liquid under the action of an electric field is calculated. The charge is transferred both by ohmic current through the interface and by the convective component over the interface. A solution quadratic in the parameter that is the ratio of the electric pressure to the capillary pressure is analyzed. Conditions where the drop transforms into a spheroid that is prolate or oblate along the electric field vector are found. An experimental study of the drop deformation by electric forces is carried out.
