例句与用法

1. So it is especially suitable for producing a duct with a large sectional area
   特别适用于管道截面面积较大的风管。
2. Finally , fibers " position distribution on the radius of pipe was counted , and it was obvious that the increase of re numbers spurred fibers " position diffusion
   最后统计了纤维在管道截面上的位置分布，明显可以看出此时re数的增加加速了纤维在管道截面上的位置扩散。
3. This paper can provide a scientific basis for design and construction in reinforcing pipeline foundation , reduction of loads on pipe , section design of pipe , and security evaluation of pipe
   本文研究的方法和成果，将为地下管道以及管基加固的设计与施工、管道减荷、管道截面设计、管道安全性判别等提供了一定的方法和理论依据。
4. The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same , and the flow quantity is enough , pipe before primary valve should be thin and long , and the pipe after primary valve should be thick and short , the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising , and spending more time in establishing pressure and flow quantity
   仿真表明,阀门过流面积在满足大于管道截面积40 %的条件下应尽可能小;在管道总长一定并满足流量要求的条件下,主阀前应采取长而细的管道,阀后则应采用短而粗的管道;上下游微小的压力波动都会严重增大开关阀门引起的水击,并使压力、流量的建立需要更长的时间。
5. And this numerical result is similar to the experimental result . then , the computation was played on different domain , rate of fibers and st numbers and got the conclusion that the farther the distance between the domain and the center of the pipe was , the more fibers " axis concentrated on the orientation of flow , while the rate of fibers and the st numbers had little influence on the distribution
   然后通过考虑管道截面上的不同区域、改变纤维长径比和st数来研究他们对纤维偏角分布的影响，从而得出结果：随着计算区域从管道截面的中心向壁面的转移，纤维粒子的偏角分布逐渐集中于低角度；而纤维长径比和st数却对纤维的偏角分布没有明显影响。
