| 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. | The nature of sand movement depends on the particle size, shape, and specific gravity in respect to the associated velocity and turbulence . 泥沙运动的性质取决于颗粒的大小、形状和比重并与流速和紊动有关。 |
| 3. | 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。 |
| 4. | The sediment transport database has been put up 建立了泥沙运动数据库。 |
| 5. | Five basic problems , which relate with sediment transport , have been discussed 探讨了与泥沙运动有关的五个基本问题。 |
| 6. | The mechanics of sediment - laden flow has been one of the most important subjects in hydraulics and river dynamics 挟沙水流的运动规律是泥沙运动力学中最基本、最重要的研究课题之一。 |
| 7. | Coast hydrodynamic factors involve wind , wave , water current , tide and corresponding sand movement etc . coast hydrodynamic environmental in island are great complicated 海岸动力因素包括影响海岸工程的风、浪、流、潮汐等诸因素和相应的泥沙运动。 |
| 8. | Based on the study of sediment transport under the actions of tidal currents and wind waves , a mathematical model of suspended load and bed load for yangtze estuary is developed 摘要通过对长江口径流、潮流和波浪共同作用下的泥沙运动规律的研究,开发并建立了长江口全沙(悬沙和底沙)数学模型。 |
| 9. | This database include 9112 sets of experimental data and 6013 sets of natural river data . compared with existing sediment transport database , the database of this paper have more data sets than others 该数据库包含9112组实验室水槽资料和6013组天然河道资料,与前人所编的泥沙运动数据库相比,资料的数目大大增加。 |
| 10. | Based on the study before , dimensional analysis is used to get similar rule of the silt movement . limitations of the similar relations based on the experience formulas of silt movement directly is overcomed 在前人研究的基础上,采用因次分析法,说明了泥沙运动的相似要求,克服了直接用经验公式确定相似关系的局限性。 |
