摘要 二阶椭圆问题是有限元方法中经常研究的问题,利用混合元格式研究该问题经常会遇到.针对二阶椭圆问题构造了一个新的非常规Hermite型矩形单元,在此基础上定义了一个新的插值函数,并构造了一个混合元格式,给出了该格式的收敛性分析. The second elliptic problem often appears in the research of the finite elelment,the form of mixed element is usually studied in this problem.A new unconventional Hermite-type Rectangular Element is constructed for the second elliptic problem.A new Interpolation function and the form of mixed element is definted.At the same time,the convergence analisis is given.
