本文研究了在交变电压作用下，沿平板电容器一个极板内表面流下的粘性介质流体薄膜表面上的波。结果表明，从不均匀电场作用的体积力是可以忽略不计的长波的情况下，电场的影响减少到膜表面上的附加压力的影响。在长波近似下，导出了确定膜厚与未扰动值的偏差的模型方程。给出了该方程的一些数值解。
Waves on the surface of a thin film of a viscous dielectric fluid flowing down the inner surface of one plate of a plane capacitor with alternating voltage applied is considered. It is shown that the volume forces acting from the inhomogeneous electric field are negligibly small in the case of long waves, and the influence of the electric field reduces to the influence of additional pressure onto the film surface. A model equation for determining the deviation of the film thickness from the undisturbed value is derived in the long-wave approximation. Some numerical solutions of this equation are given.
