| 1. | When flow velocity decreases below the corresponding incipient motion condition, no sediment movement occurs . 当水流速度小于相应的起始运动时,将无泥沙运动。 |
| 2. | Despite this attention; only modest progress has been made in the basic understanding of the bed phenomena and their relation to sediment movement . 尽管受到注意,但床面现象及其对泥沙运动的关系的基本理解却仅有不太显著的进步。 |
| 3. | Analysis on flow and sediment movement in approach channels of tidal river branches 感潮河段船闸下引航道水沙运动及泥沙淤积 |
| 4. | Influence of the tunnel cros sing the yellow river in south water to north project on flow and sediment movement 穿黄隧洞束窄河道对河段水沙特性的影响分析 |
| 5. | Cultivation of slope farmland influences surface runoff and sediment movement on slopes 摘要坡耕地由于人为耕作管理作用,造成地表高低起伏,影响著坡面地表径流和产沙。 |
| 6. | According to adcp data and suspended sediment concentration , suspended sediment movement in the yangtze river estuary is studied 摘要采用adcp实测水流资料与悬沙含量实测资料相结合的方法,对长江口悬沙运动进行分析。 |
| 7. | Considering the effects of both tides and waves , a2 - d numerical model was used to simulate the sediment movement in lianyungang harbor , and a large scaled average sediment concentration field of hai - zhou bay was computed 摘要以连云港进港航道为例,应用波浪、潮流共同作用下的二维泥沙数学模型,研究淤泥质海岸的泥沙运动及航道回淤问题。 |
| 8. | Finally , the equations of the velocity when the particles start to move , suspend and stop were gotten from the rule of silt sediment movement . the velocity with no depositting was gotten from a equation of silt sediment movement in drainage 最后又借用泥沙运动方面以及污水管道内泥沙运动方程的知识,得出了不同管径下颗粒的起动、扬动、止动流速与管道运行临界不淤流速。 |
| 9. | Based on the prototype observation and model test made for the periodic - flushing de - silting basin , the process and the division of the three - stage hydraulic flushing are put forward on the basis of the feature of water - sediment movement , and then the calculation formulas and the related parameters for the stages of emptying flushing ; retrogressive flushing and the flushing along the basin are given as well 摘要依据定期冲洗式沉沙池水力冲洗的原型观测和模型试验,根据水沙运动特征,提出定期冲洗式沉沙池水力冲洗三阶段冲洗过程及划分,分别给出泄空冲洗、溯源冲洗和沿程冲洗各阶段的计算式和有关参数。 |
| 10. | According to the theories of the energy dissipation of wave - water and sediment movement and based on the bottom sediment load formula developed by dou guoren , a formula to calculate the transport of the bottom sediment , which includes the bed load and part of suspended load , under the joint action of waves , tidal currents and wind - currents is derived 摘要根据波动水流能量及泥沙运动原理,参考了窦国仁推导底沙输沙量的方法,推导出波浪、潮流和风吹流共同作用下的底沙输沙量(包括推移质和部分悬移质输沙)计算式。 |
