泥沙粒径 meaning in Chinese
sediment grain size
Examples
- The toad nutrient of floods increases as the sediment concentration increases , and there is nearly a linear relationship between them , by analysing the particle size of the sediment , we can conclude that the reason of the liner relationship is the resourse of flood nutrient and the sediment nature
通过对洪水中下层泥沙做颗粒级配分析，推断出这种结果主要是由洪水养分成因及洪水中下层泥沙粒径特性决定的。 - The process of effluent flow during loading in self - propelled trailing suction hopper dredgers was simulated by way of physical modeling and was measured and analyzed by using the flow rate and concentration of spoil in the hoppers , particle sizes of sediments at the inlet and outlet of the effluent flow pipe and hopper volume as the major control parameters
摘要通过物理模型试验模拟自航耙吸挖泥船装舱溢流施工过程，以舱内流速、舱内浓度、溢流进出口泥沙粒径、装舱量几方面为主要控制因素，进行实测、分析，并比较自航耙4种常用装舱装置的消能效果。 - Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir , the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed , and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach
摘要根据刘家峡水库变动回水区的河段地形特征和历年河床质泥沙粒径级配资料，分析了变动回水区河段淤积和冲刷时，河床质泥沙中值粒径的沿程变化和历年河床质泥沙中值粒径变化过程，并指出粒径分布由粗变细的转折点在变动回水区寺沟峡峡口处。
