摘　　要：利用分析技巧得到了Post-Gamma算子一阶绝对矩量的渐近估计式,并结合区间分割技术和Bojanic-Cheng方法研究了Post-Gamma算子关于导函数为局部有界函数的点态逼近估计,同时得到了Post-Gamma算子的几何性质.An asymptotic approximation of first order absolute moment for Post-Gamma operators is obtained by means of analysis technique. The pointwise approximation of Post-Gamma operators for functions with locally bounded derivatives is studied by the combination of Bojanic-Cheng methods and the division technique of interval. At the same time, the geometry properties of Post- Gamma operators are obtained.
