During the operation of storing water and retaining sediment, serious deposition in the reservoir leads to backwater level rising rapidly. Therefore it also brings out new river-trained theory of design sediment load and integrated regulation of water-sediment.

开始蓄水拦沙运用，水库严重淤积回水迅速上延，引发设计输沙量和水沙综合调节治河新理论。

The result shows that the sediment resource of the Laizhou gulf is made up of the Yellow River mouth sandspit and the Laizhou shoal, which origin from the Yellow river sediment and the river sediment of the north-west Shandong peninsula.

结果表明，莱州湾泥沙资源主要包括黄河口沙嘴和莱州浅滩两部分，分别来源于黄河和山东半岛西北部河流输沙。

The paper analyzes and calculates the sediment coming from the sea by utilizing the observed hydrological and tidal data of the Yellow River estuary.

利用黄河口实测水文及潮汐资料分析计算了海向来沙情况。

The Hg, Pb, Zn average contents in sediment of Wuli River which was contaminated by chlor-alkali were 663,3.21, 5.51 times as high as the regional sediment background value, respectively.

结果表明：源于氯碱厂Hg污染的五里河沉积物中Hg，Pb，Zn含量平均值分别超过区域沉积物背景值662,2.21,4.51倍；

The sediment size changes sharply in two reaches of the middle and lower Yangtze River. Sediment type changes from gravel into sand in one zone, and another from sand into mud.

长江中下游河床沉积物在两个河段出现了粒径的急剧变化和沉积物类型的转换，一个是从砾石转变为砂，另一个是从砂转变为泥。

On the basis of the stressing features of sediment particles on the river bed surface, the probability distribution of instantaneous initiation moment of sediment particles' motion was deduced to be a normal distribution.

根据位于床面上泥沙颗粒的受力特点，取各力力臂为常量，推导得到泥沙颗粒瞬时起动力矩的概率分布为正态分布。
