| Abstract: | In this paper,the approximation of the interracial and differential equation with interracial boundary condition is studied with the anisotropic biquadratic element.By means of integral identities techniques and a postprocessing technique,based on the special properties of the element the super-close property and super-convergence are obtained without Ritz-Volterra projection and any modification on anisotropic meshes. |
