| 1. | When two beds are connected their levels equalize .
当两个床层连通时，它们的床面自行找平。 |
| 2. | In the upper reach the bed was dune covered and in the lower reach it was flat .
上游河段的床面为沙垄所覆盖，而下游河段则为平整床面。 |
| 3. | When erosion ceased, the bed surface was observed to be covered by a thin layer of sticky material .
当冲刷停止时可以观察到床面上覆盖着一薄层粘着物质。 |
| 4. | For some sediments and flow the flat bed does not occur and the bed form goes directly from dunes to antidunes .
对某些泥沙和水流，平整床面并不发生，而床面形状则直接从沙垄转为逆行沙垄。 |
| 5. | 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。 |
| 6. | 4 . the movable - bed resistance problem has been studied

方柱尾流流态对床面冲淤形态的影响 |
| 8. | The concentration distribution becomes uniform near the bed due to dispersive forces
由于床面附近颗粒受到离散力的作用，近底区浓度分布趋于均匀。在0 |
| 9. | In the near bed region , the turbulent intensities are elevated above those of water at a rate proportional to particle size due to collisions and velocity gradient
床面附近，颗粒脉动强度大于流体的脉动强度，且粒径越大，脉动强度越大。 |
