摘　　要：以曼宁公式和经典水力学基本理论为基础,探讨了不同枯落物室内糙率系数(n)的试验方法,并系统地对该方法中各试验步骤、试验数据计算和数据整理分析过程进行了详细介绍,同时还指出了试验中应注意的问题.This paper,based on Manning Formula and the theory of classical hydraulics, the method of experimentation and studying on the roughness coefficient n of varied litter in laboratory has been researched.The steps in the experimental process,the calculation of ex- perimented data,and the process of the data analysis have also been explained in detail.And at the same time the paper points out the problems which should be noticed in the experimen- tation.
