摘　　要：本文讨论了二阶双曲方程的非协调W ilson有限元逼近。通过新的技巧和方法在各向异性网格下给出了与传统有限元方法完全相同的最优误差估计。In this paper, the nonconforming Wilson finite element approximation for the second order hyperbolic equation is studied based on some new techniques and approaches. The optimal error estimates for convergence are obtained under anisotropie meshes, which are as same as the traditional finite element methods.

关 键 词：二阶双曲方程 非协调Wilson元 各向异性 最优误差估计
