| 1. | Bed material samplers, as first developed, may be divided into three types .
最初的河床质取样器有三种类型。 |
| 2. | As the sampler is dragged along the bed, it collects a sample from the top layer of bed material .
取样器沿河底拖动，收取表层河床质。 |
| 3. | Technical standard for measurements of bed load and bed material in open channels
河流推移质泥沙及床沙.测验规程 |
| 4. | Bed material load
底部物质负荷 |
| 5. | Liquid flow measurement in open channels . sampling and analysis of gravel - bed material
明渠液体流量的测量.砾石河床材料分析和取样 |
| 6. | Basic equation for variation of bed material composition in active layer of alluvial river
冲积河流混合活动层内床沙级配变化的动力学基本方程 |
| 7. | It has been proved , the bed material load , wash load and total load follow the same rule of carrying capacity
证实了床沙质、冲泻质与全沙具有统一的挟沙能力。 |
| 8. | Measurement of liquid flow in open channels - sediment transport - sampling and analysis of gravel bed material
明渠流量测量.第10部分:沉积物夹带.第10e节:砾石河床材料取样和分析 |
| 9. | The effect of lateral boundary condition , the river regime and the bed material on lateral erosion are analyzed
结果表明：水库下游均会有河岸侵蚀发生，但初期一般以下切为主，后期以展宽为主。 |
| 10. | Measurement of liquid flow in open channels - sediment transport - guide to methods of sampling of sand - bed and cohesive - bed materials
明渠流量测量.第10部分:泥沙挟带.第10c节:砂床和粘性河床材料取样方法导则 |
