摘　　要：讨论了各向异性窄四边形元的能量模和零模估计,并利用此单元求解线性抛物型方程,得到了半离散格式和全离散格式的误差估计。In this paper,anisotropic narrow quadrilateral finite element method for parabolic equations are proposed. At first We give the energy norm and norm estimates of anisotropic narrow quadrilateral finite element, then we prove the estimates of se midiserete form and fulldicrete form of parabolic equations.
