摘要
本文针对一类二阶椭圆型偏微分方程组的边值问题，提出了有限元算法，给出了有限元近似解在Ｌ２，Ｈ模下的最优阶误差估计式．
In this paper,we discuss the finite element method for a class of second-order elliptic systems of partial differential equations with boundary value problems,and prove that the Galerkin approximate solutions have optimal order error estimates on H 1 and L 2-norm.Numerical example shows this algorith is effective.
