中文摘要：

基于速度和磨擦速度的电源功能，速度侧面被获得。由解决 Schmidt 的散开方程，平衡推迟了沉积集中侧面进一步被推出。速度和推迟的沉积集中的侧面与这域同意推迟的沉积集中的数据，和侧面避免无理性很好古典在水表面唤醒象零值那样的侧面。根据这些侧面，为计算推迟的沉积运输率易用的表情被导出。

英文摘要：

Based on the power function of velocity and the friction velocity,a velocity profile is obtained.By solving the Schmidt＇s diffusion equation,an equilibrium suspended sediment concentration profile is further deduced.The profiles of velocity and suspended sediment concentration agree well with the field data,and the profile of suspended sediment concentration avoids the unreasonableness of the classical Rouse profile such as a zero value at the water surface.According to these profiles,an expression which is easy to use for calculating the suspended sediment transport rate is derived.
