摘　　要：从求解拉普拉斯方程入手,利用极限条件和边界条件推出了介质球在点电荷电场中产生的电势分布规律,并由此推出了当介质球的电容率ε→∞时,介质球在电场中为等电势体.Based on the limit and boundary conditions, Laplace Equation is used to calculate the distribution of the electric potential produced a medium ball in a point charge electric field. It is deduced that the medium ball with infinite capacitance is an equi-potential body in the electric field.

关 键 词：介质球 点电荷电场 电势 电容率
