摘　　要：利用导体曲面函数,将求解拉普拉斯方程转变为积分运算,从而得到了在无电荷区域普遍成立的电势表达式,再通过边界条件导出共焦抛物导体柱板间的电场分布,并给出了电场线方程.Using the conductor surface function,the Laplace equation is transformed into the integral operation,and the potential expression is obtained which is generally established in the no charge region.Then the electric field distribution between two confocal parabolic conductor plates is calculated by the boundary condition,and equations of the electric field line is given.

关 键 词：抛物柱板 电势 电场强度
