该文利用散度空间的性质,给出了一些非协调板元误差估计的新方法,得到误差的能量模和L~2模的估计.较以前的方法更直接简便,并且能够达到所要求的阶数.
In this paper,some new methods of error estimates for nonconforming plate element is given according to the properties of divergence space.The error estimate of energy norm and L~2(Ω) norm is proved.Compared with the former methods,it is more direct and convenient, and it also obtains the order required.
