| 摘 要： | 非均匀沙推移质输沙率是生产中的一个重要问题，由于测验困难，许多河流尚无系统的原型观测资料。目前计算非均匀推移质输沙率的公式相差较大，难以得到统一的结论。本文利用实验及实测资料分析推移质输沙率的脉动特性，用负幂律分布进行描述，表明具有一定的普遍性。

| Abstract: | Bed load trabsport rate is an important problem in the development of rivers of gravel.Due to the difficulties in field measurement,there is still lack of systematic data in many rivers.Nowdays,the results of many formulars of non uniform sediment transport rate are too different to get the same value.This paper studied the stochastic features of bed load transport rate of non uniform sediment with the distribution of negative exponnent,this result was feasible. |
