汊道 meaning in English
inlet
Examples
- The main problems in waterway regulation on branching rapids of mountain rivers are choosing navigation paths and improving flow condition
山区河流石质汊流急滩航道整治主要解决选择通航汊道和改善航道水流条件的问题。 - Analyses show that , when the ratio of the two branches ' discharge widths is coordinated with the resistance ratio of the two branches , the project reach has the least resistance , that the discharge capacity is the largest and that its influence on the project reach is less after the finishing of the project
通过分析，当两汊泄流宽度之比与汊道两汊阻力比相协调时，枢纽河段的阻力最小，其泄洪能力达最大，且枢纽建成后对枢纽河段的影响也较小。 - 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。 - On the other hand , the velocity may also be increased by excavating another channel , which should be treated cautiously . ( 2 ) the change of flow rate in a typical branching rocky channel is related to excavation area scope and mode . more excavation area scope and width , more increase in flow rate
( 2 )石质汊流滩汊道分流比的变化一般与汊道的开挖面积、开挖范围以及开挖方式等因素有关，即开挖面积越大，则分流比增加越多；开挖范围越广，分流比增加越多；相同开挖面积情况下，宽浅开挖比深窄开挖对分流比的影响要大。 - ( 3 ) in excavation channel , the velocity in engineering area may be reduced , but the velocity in other areas of this channel may be increased and the flow condition may be deteriorated as a result of the increase of flow rate in this channel . thus , it should be discussed and studied before engineering practice
( 3 )在汊道的开挖中，工程区域的局部流速可能有所下降，但因分流比有所增加，可能导致其余部分河段的流速有所增加，恶化航行水流条件，因此在工程前需要进行充分的论证和深入的研究。
