摘要 利用具有各向异性特征的双线性元和双二次元构造了协调mortar有限元空间,摆脱了传统意义下对网格要求的正则性条件或拟一致假设;利用积分恒等式技巧得到了与传统方法完全相同的超逼近结果. The conforming mortar finite element with anisotropy was studied without regularity assumption.Meanwhile,superconvergence results coincides with the conventional methods were obtained by means of intergeral identities techniques.
