sectional area
Examples
- Area of steel
钢筋断面面积 - The calculated result from an example shows that the stable sectional area reduces with the increase of working head , or the decrease of the tailrace tunnel length
计算结果表明，尾水调压室断面面积随水轮机工作水头的增大或尾水洞长度的缩短而减小。 - Under the chosen conditions of testing discharge - sediment and scheme of dredged section , the effect of dredging river for deposition reduction will be considered better when the dredged section ' s wide deep radio is - ^ b ~ nlhn with 6 ~ 9 and dredged section area is about 250 ~ 300m2
在选定的试验水沙条件和挖河断面方案下，认为开挖断面面积在250 300m ‘左右，断面宽深比vb 。 m在6 9之间挖河减淤效果11 。 - 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。 - 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。
