【Abstract】 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.更多还原
