摘　　要：本文应用了Adini非协调元方法研究了在各向异性网格下的四阶Bi-wave方程边值问题,通过积分恒等式等方法得到了相应的超收敛结果。The main aim of this paper is to study the approximation to bi-wave equation with the nonconforming Adini finite element on the anisotropic meshes. The super Convergence property of the exact solution is obtained by＂ means of integral identities techniques.

关 键 词：Bi—wave方程 Adini非协调有限元 误差估计 各向异性 超收敛
