摘　　要：应用有限元法 ,将泊松方程不能直接求解的二维静电场分布问题转变为一个变分问题 。Applying the method of finite element method, problem on two-dimensional electrostaic field, which can't be solved directly by Poisson equation, is changed into the variational problem.Ultimately this method has been inducted into the problem of solving the linear equations.
