水流

You can redirect each of these streams to or from a file.

你能重新传入每一条这些水流到或从一个文件。

A 3D particle velocity measurement system was built upon calibration method of multi-layer regular grid and particle space coordinates determination method of iterative approaching developed in this paper.

对不同的粒径和不同的水流条件，颗粒纵向平均速度都符合对数分布规律，垂向和横向的平均速度属于随机波动的范围。

On the basis of regular wave transformation equation in a reference[1] incorporating comprehensively environmental current,nonlinear dispersion effect,rapidly varying topography effect,energy loss due to bottom friction,refraction and diffraction, the governing equations are derived for irregular multi-directional wave transformation incorporating multi factors according to the principle of superposition of linear wave and the wave directional spectrum theory.

1引言波浪在由外海向近岸的传播过程中，由于受到复杂地形、障碍物和水流等因素的影响，波浪传播将发生变形。文献[2]对描述波浪在近岸传播变形的各种数学模型方法做了较为全面的、系统的回顾和总结。

The roar of rushing water is reverberating in the gorge.

水流的轰鸣声在峡谷里回荡。

The flexible vegetation is a main kind of engineering materials in the ecological revetment engineering, because it grows quickly and is easy to be planted and constructed.

但是目前对于草本植物与水流之间相互作用的认识还很模糊，尤其是采用草皮护岸后对于原有河岸的糙率改变情况缺乏系统的研究。

It is found that water velocity vertical distribution under ice-cover is influenced mainly by the relative size of channel roughness and ice-cover roughness, less by the water depth and not sensitive to the variation of Reynold number as well, which is relatively uniform in the flow core and deviates from the logarithmic law.

结果表明：冰盖下水流流速垂向分布主要受床面与冰盖粗糙度的相对大小影响，受水深影响较小，对雷诺数变化并不敏感；在流动核心部分分布较为均匀，并不遵循对数分布规律。

For the case of the joint actions of the right-angled waves and current,the current has large effect on the motions of the tunnel element.

对于正向波流联合作用的情形，水流对管段的运动有很大的影响。

The velocity of flow on soil surface can be measured and may be used to explain the mechanism of rill erosion.

细沟流中水流速度沿流线方向的垂直分布是一个非常困难的问题。要研究这个问

No need to install the valve In the maintenance of a ring circuit, it can close the loop on the balance valve, balance valve at this fire pumps time to play the role of water cut off valves, repair is completed and then revert to its original locked position.

不必再安装截止阀在检修某一环路时，可将该环路上的胶体磨平衡阀关闭，此时平衡阀起到截止阀截断水流的作用，检修完毕后再回复到原来锁定的位置。

Far from the rip-roaring Milan and alluring Florence, the countryside sun, creeks, birds, lizards and vegetation were his best teachers.

望看芬奇远处如画的景致，思绪不禁飘得更远：漫游在乡间的达芬奇此时还不知道佛罗伦萨的喧嚣与米兰的诱惑，这里有飞鸟、阳光与水流，大自然是他最好的老师。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
