摘　　要：构造出一种递推的Kantorovich型算子,利用算子分解技巧研究了其在经典空间上的收敛性和逼近特征,并给出更加精细的渐进展式以及逼近度估计.A kind of recursive Kantorovich type operators is constructed.Using decomposition technique of operators,the convergence for these operators and approximation characteristics on classic space are studied.The more sophisticated asymptotic behavior and an estimation of degree of approximation are obtained.

关 键 词：KANTOROVICH算子 收敛 渐进展式 逼近度
