油中水球静电极化束缚电荷面密度的分布

采用旋转椭球模型模拟油中水球极化后的形状，将其视为椭圆边界的物理问题，通过儒可夫斯基的正反变换，求解椭球内外的电势、电场，再由电介质的性质和椭圆有关性质，得出了束缚电荷面密度的表达式，并引入了相对束缚电荷面密度概念，得出相对束缚电荷面密度的分布与束缚电荷面密度分布两端增强中间减弱，随着D值增大，束缚电荷面密度由端点到中点的衰减率增大等结果。

The Distirbution of the Polarized bound Charges Surface Density on the Water Ball in the Oll

The bound charges surface density was stud ied after the shape of water ball in the oil changed under static extermal electric field polarizing,the shape was simulated by the model of the rotate ellipse, and regarded as sphysics problem of the elliptical boundary,through positive and negative XYKOCKN transformation,the electrostatic potential and the field was found a solution,the formula of the polarizing bound charges surface de nsity was deducde from the properties dielectric and ellipse.The comcept of the relative to bound charges surface density was introduced.The distribution of the relative to bound charges surface density was the same as the distribution of the bound charged surface density.It was analyzed that the action of the breakdown process bound charges surface density was in the oil,possibly,“water branch” and “oil branch”were process bound charges surface density was in the oil,poss ibly,“water branch”and “oil branch” were produced.The larger external field, the larger D numerical value,the distribution of the bound charges surface density was incredasing at tow ends and reducing at middle, Dnumerical value increasi ng,there was a result that the reduced rate of the bound charges surface density was increasing from the end to the middle.
