一类椭圆型方程的非标准线性元的渐近展式舒适，黄云清［摘要］＊本文通过对系数及右端进行线性插值而得到近似有限元解，证明了的渐近展式和标准有限元完全相同．主题词：有限元；渐近展式；非标准有限元分类号：Ｏ２４２．２１１引言有限元解的渐近展开式的研究在有限元...

In this paper we consider a elliptic boundary value problem approximated by a modified F.E.methods.Here,the coefficients and right-hand side of the equations are approximated by bilinear interpolation.We obtain the same results as what we can do for the standard F.E.methods.
