摘　　要：给出了二维投影型插值的构造,并验证了二维投影型插值具有各向异性特征,利用各向异性单元分析方法得到了各向异性网格下对二阶椭圆问题的有限元误差估计.The construction of two-dimensional projection interpolation was given. It was proven that the two-dimensional projection interpolation had the anisotropic property. Using the analytic method of the anisotropic element, error estimate of the second order elliptic problem was obtained.

关 键 词：投影型插值 各向异性 误差估计
