摘要
本文通过对泥沙颗粒在水中的受力情况分析，从理论上导出了描述推移质运动的数学表达式．在此基础上，又导得了挟沙水流的底部含沙量，从而使泥沙运动的扩散方程能够方便地运用到工程实际问题之中．
In this paper,the forces acting on sediment particle and the movement of sediment particles in channel flow are studied and then the formula calculating bed load is derived theoretically. The calculated results are in good agreement with observed data.
