| 1. | In approximately 1925, work began on the problem of suspension . 大约在1925年才开始了关于悬移质的研究。 |
| 2. | Code for measurement of sus pended sediment in open channels 河流悬移质泥沙测验规范 |
| 3. | Code for measurements of suspended sediment in open channels 河流悬移质泥沙测验规范 |
| 4. | Bedload is the main factor resulting in bed form for few sands of suspend load in the river bed 河床质中几乎没有悬移质颗粒,对河床演变起主要作用的是推移质泥沙。 |
| 5. | Consequently , the generalized suspended sediment concentration profile suggested by ni ( 1989 ) is derived directly from the basic governing equations 从而对倪晋仁和王光谦提出的悬移质泥沙分布的统一公式给出了理论解释。 |
| 6. | We also found that the wide - sediment capacity in water and the ability of holding sediment increase along with increase of sediment in water 另外,通过对泾渭两河上的水文站实测悬移质级配成果进行分析,可以发现,随含沙量增加,粗沙含量增加,挟沙能力增加。 |
| 7. | The results of model experiment proved that the new - type setting basin can greatly improve the deposition efficiency of suspended sediment and help the excluding of silt 试验结果证明,这种新型冲洗式沉沙池可以大大提高沉沙池对悬移质泥沙的沉淀效率,并有利于泥沙的排除。 |
| 8. | A ptv system was developed which allows particle velocities across a flow plane to be measured at a single instant . ptv presents a new efficient technique in hydraulic measurement 该系统具有可靠的精度,能同步量测全剖面的颗粒瞬时运动信息,为悬移质运动量测提供了崭新的技术手段。 |
| 9. | The additional resistance caused by sediment transport of bed - load and suspended load is derived from mean energy equation of sediment - laden flow , and the variation of resistance in sediment - laden flow is discussed 从挟沙水流的平均能量方程出发,得到了推移质附加阻力的计算公式及悬移质附加阻力计算公式,并对挟沙水流的阻力进行了讨论。 |
| 10. | In this paper , a numerical simulation model to analyze the function and effect of the pumping irrigation in sediment deposition reduction of the irrigation canal system is proposed 除了以往有效的措施外,本文在总结灌区渠道不同部位设置提水泵站设施作用与效果的同时,通过建立灌区渠道悬移质冲刷计算模型,对其减淤清淤的作用与效果进行了理论分析研究。 |
