摘要
利用蔡查罗平均值得出了有理函数的积分表达式，然后得到有理函数的Ｐ次平均偏差估计式（０＜ｐ≤１）．这个估计式改进了．Ａ．［３］的结果．
The integral expression of rational function is obtained with Cesaro mean in this paper,then theauthor reaches the estimate expression that is about p-degree mean deviation of rational function (0<p≤1 ).The estimate expression improves the tesult obtained by . A. [3]
