At upper flow regime, the total stream power gradually deviate the effective stream power from movable plane bed to existence of sand wave.

在高能态区，从动平整床面到沙浪的出现，总水流功率又逐渐背离有效水流功率。

Based on sediment transport experiments, the interaction between flow and sediment movement is analysed and the problems of grain resistance and bed load transport on plane movable bed are discussed.

本文在输沙实验的基础上，从研究水流结构着手，分析了水流和泥沙之间的相互作用关系，讨论了动床沙粒阻力和底沙输移规律。
