摘　　要：本文考虑重调和方程的Ｃ０非协调元逼近．通过双线性型ｃｋ（ｕ，ｖ）引入的补偿和将多重网格法应用到Ｃ０非协调板元，给出了更精确的逼近．In this paper,we conside C 0 nonconforming finite element approximation of the biharmonic equation.By the introduction of the compensation for the bilinear form c k(u,v),the more accurate approximation is obtained when multigrid algorithm is applied to C 0 nonconforming plate elements.
