摘　　要：针对均匀电场作用下介质球周围电场分布情况,建立了二维电场数学模型,采用有限差分法,对场域内的Laplace方程和边界条件进行离散化,得到了均匀电场作用下介质球周围及其内部的电势及电场分布的数值解,并从理论上验证了该数值解的准确性。A mathematical model was established to predict the electric field distribution about the medium ball in uniform electric field. By solving the built equation for electric field, with limited difference, The numerical simulation results were obtained. The numerical simulation results presented are in good agreement with theoretical analysis.
