采用机理分析的方法，推导相关物理及力学公式，得出曼宁系数与四面六边透水框架尺寸的关系，再由传递性得到框架长的平方与减速率呈正相关，得到它们的关系表达式为η＝Aa2＋Ba ＋C （A，B，C系数常量）。通过水槽实验，对测得的数据进行数据拟合，结果显示与机理分析得出的结论相同。本模型科学、严密，提高了实验分析所得结果的准确性，可用于实践。

By analyzing the mechanism the relevant physical and mechanical formula that Manning’s rela-tionship with the first draw frame size were derived,and then permeable frame length was positively correla-ted with the rate of deceleration was gotten by the transitive,and their relationship expression was η=Aa2 +Ba+C(A,B,C coefficients are constants)was finally gotten.Through the relevant tank test,the ex-perimental data could be measured,which was obtained for the experimental data fitting,and the same re-sults and conclusions of the analysis mechanism were found.Advantage of this model was a mathematical method of analysis and data fitting mechanism,which improved the accuracy of the original analysis of the results of the experiment,and therefore could be used in practice .
