- Example Sentences:
| 1. | Flow cross - section
过水断面 | | 2. | The main measures are : damming improving flow condition riverbed excavation etc . riverbed excavation is always used in reducing velocity of a channel with bad flow condition . in singularity channel , velocity can be reduced with the increase of crossing area by excavating riverbeds
整治采取的主要措施有：筑坝壅水、改善流态、开挖河槽等等，对于流态恶劣的急流滩，常采用开挖河槽扩大过水断面面积的方法来降低航道流速。 | | 3. | A 2 - d hydrodynamic - numerical model was applied to typical rocky rapids called jiyutan by comparing different computational models . based on the comparison of different schemes , the change of the discharge and the flow current in a branch were analyzed , and the relationship between the flow condition and excavation area , scope as well as mode was discussed , the conclusions show : ( 1 ) in a branching rocky rapids , the velocity may be reduced and flow condition can be improved by excavating one channel partly
本文在对各种数学模型比较的基础上，应用二维水动力数学模型研究典型石质汊流滩? ?广西浔江鲫鱼滩航道整治工程方案，通过各方案计算结果比较，分析了不同汊道的开挖及汊道内不同开挖面积、开挖范围以及开挖方式所引起的分流比及工程区域航道水力条件的变化规律，研究结果表明： ( 1 )对于石质汊流滩来说，在某一汊道通过局部开挖河槽，扩大过水断面面积，可以达到降低工程段流速、改善局部水流条件的目的。 | | 4. | The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space , increasing the capillary resisting force to soil moisture , and decreasing the water potential gradient because of the increasing of movement distances of soil water
导水率减小是冻结土壤入渗能力减小的根本原因，而土壤中液态水的相变是导水率减小的根源所在。土壤水分的相变及其膨胀通过减小土壤水分过水断面面积和孔隙孔径，增大阻力和由于增长运动距离而减小水势梯度使冻结土壤的导水率降低。 | | 5. | ( 5 ) the maximum water level risen by the enclose tideland cultivation around the reservoir is 0 . 66m , the responding quality is 2000mvs , which heavily effect the environment around the reservoir . the reservoir " s water level is risen because cross section and flood canal become narrow , which caused by building dam , this makes groundwater unsmooth , drainage , even flow from a lower to a higher space and soil salinized
66m ，且为2000m ’儿的常年洪水，对库区周边环境的影响较大，因打坝筑堤缩小过水断面和行洪通道造成水库水位进一步抬升，致使库区周边灌区地下水排水不畅，乃至倒灌，型成士地盐碱化。 | | 6. | Excavating riverbeds in one channel may not only reduce the velocity area in some areas but also increase the velocity in other areas by increasing flow rate in this channel without correspondent changes in riverbeds of rocky rapids . in result , the velocity in waterway may be increased instead of be reduced , the flow condition may also be deteriorated . thus , which branch should be excavated and how to excavate in improving the flow condition of the branch should be further explored
但在分汊河道内，情况较为复杂，在一汊河道内采取开挖措施后，虽然其过水断面有所增加，局部流速相应降低，但是由于工程后，汊道的分流比将会相应变化，而石质河床一般无法通过冲淤变化以适应水流条件的改变，因此，航道内工程处的流速可能降低，也可能不降反而有所增加，恶化了航道的水流条件。 | | 7. | So far as the aqueduct with large discharge and lower head is concerned , the non - uniform flow will occur in the aqueduct , when the discharge is enlarged after the water - carrying section being determined based on the design discharge and the given head ; for which the flow condition must be presumed , so as to determine the water surface profile
摘要大流量低水头渡槽根据设计流量和给定水头确定过水断面后，通过加大流量时，渡槽内就会发生非均匀流，需对这种水流情况进行推算，以确定渡槽在通过加大流量时的水面线。 |
