The deformation of hemispherical bubbles under vertical static electric fields was studied using a plane capacitor. The deformation and the bubbles shape have been monitored according to the amplitude of the electric field and the initial volume of the bubbles. Two different substrates, a dry solid plate or a liquid pool, were used to inspect the influence of the pining of the contact line. The deformation of sessile (on dry solid plate) and floating (on a liquid pool) bubbles were compared. The deformation parameter has been rationalized using a simple model. More precisely, the number of interfaces has been found to be a relevant parameter that imposes the shape of the bubbles.

均匀电场中肥皂泡的变形

使用平面电容器研究了垂直静电场下半球形气泡的变形。已经根据电场的幅度和气泡的初始体积监测了变形和气泡形状。使用两种不同的基板（干燥的固体板或液体池）来检查接触线固定的影响。比较了无柄（在干燥的固体板上）和漂浮（在液池上）气泡的变形。变形参数已使用简单模型进行了合理化处理。更精确地，已经发现界面的数量是强加气泡形状的相关参数。
