In this thesis, several nonconformingfiniteelement methods for plate problems and fourth order elliptic singular perturbation problems are discussed.
在论文中,我们主要讨论了四阶椭圆问题的一些非协调有限元逼近。

The second order elliptic problem is studied by using conforming finiteelement and nonconformingfiniteelement in the different parts of the area respectively.
在区域的两个不同部分分别采用协调元和非协调元来研究二阶椭圆问题。

Studied in this paper is the nonconformingfiniteelement approximation to the second order variational obstacle problem with displacement obstacle on the anisotropic meshess.
