摘要：
The main aim of this paper is to study the nonconforming quadrilateral finite element approximation to second order elliptic problems on anisotropic meshes. The optimal order error estimates in broken energy norm and -norm are obtained, and three numerical experiments are carried out to confirm the theoretical results.
