摘　　要：主要讨论粘弹性方程修正的P1-非协调元的收敛性.并利用该单元的特殊性质,在不需要Ritz投影条件下导出了其最优误差估计.In this paper, convergence analysis of the modified P1-nonconforming finite element for the viscoelasticity equation is discussed. By using the special properties of the element the optimal error estimates are obtained without Ritz projection.

关 键 词：粘弹性方程 P1-非协调元 误差估计
