水流

Comparing the computation results of these four design schemes we get variation of the kinetic energy correction factor near groynes in Panjiatai shoal when water depth is less than the groyne height. The variation characteristics of the kinetic energy correction factor in Panjiatai shoal is different from the experiment results because the effect of groynes in the Panjiatai shoal is simulated by three parameters together.

比较四个方案的计算结果，可以得到潘家台滩绕流流态下丁坝附近动能修正系数的变化情况，与实验进行对比，分析两者产生差异的原因是潘家台滩工程中丁坝对水流的影响由三个参数共同来模拟。

One of these 'rivers' in the Atlantic is called the Gulf Stream.

这是一股暖水流。

One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water.

大西洋中这些潮流之一称为墨西哥湾流，这是一般暖水流。

Sure, you can't predict where the water will go a half-mile downstream, but for five seconds -- or five hours on Wall Street -- you can predict the unfolding show.

没错，你确实没办法预测水流在下游半英里的地方流向何方，但是，就在那五秒钟——或者，在华尔街那边，五个小时——的时间里，你却可以对这个正在展开的显现进行预测。

The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.

本文介绍了ELCIRC的理论及使用；基于其在Linux平台下的软件XMGREDIT5生成全三角形网格并评价其特性，认为XMGREDIT5较适合大范围海域而不适用于河道；应用ELCIRC模型计算了长江口的潮流场并进行验证，结果与实测资料吻合良好，且能较好地模拟出地形变化对水流结构的影响；文中对于风场的影响作了定性分析，同时根据实际需要对模型作了改进，如将仅支持长期资料调和常数的开边界条件改为可选择的短期调和常数边界和潮位边界，使二进制格式结果文件数据输出可以处理多点数据及流场等等。

The flow field of the PCCP pipeline is simulated, so the head loss and resistance coefficient are calculated which are consistent with the test data. Additionally, other pipelines of different diameter are also simulated, and the resistance coefficient's law along with the diameter is carried out.

对PCCP管道中的水流流场进行数值模拟，计算并求解出管道的水头损失和阻力系数，与模型试验取得了较为一致的结果；另外，还对不同管径的管道进行了模拟，得到了阻力系数随管径的变化规律。

Acamas and the warrior Peirous commanded the Thracians and those that came from beyond the mighty stream of the Hellespont.

阿卡马斯和壮士裴鲁斯率领着斯拉凯兵勇，赫勒斯庞特滚滚的水流疆限着族民们生活的地域。

Take, then, your tasselled aegis, and shake it furiously, so as to set the Achaean heroes in a panic; take, moreover, brave Hector, O Far-Darter, into your own care, and rouse him to deeds of daring, till the Achaeans are sent flying back to their ships and to the Hellespont.

现在，你可拿起流苏飘荡的埃吉斯，奋力摇晃，吓返阿开亚壮勇。然后，我的远射手，你要亲自关心光荣的赫克托耳，给他注入巨大的勇力，直到阿开亚人撒腿逃跑，及至他们的海船和赫勒斯庞特的水流。

Heraclitus that the water is constantly flowing, when people enter the same river a second time, they access to the water is changed ...

赫拉克利特认为，河水是在不停流动的，当人们第二次踏入同一河流时，他们所接触到的水流已是变化了的。。。

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。
