水流

One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from the Arctic.

大西洋有一条这种&河流&，叫做墨西哥湾流，这是一股暖水流；另外一条是拉布拉多海流——这是来自北冰洋的冷水流。

Its a new war, china will block water and lakhs of chinese imperial army will stand on the dam and spray urine on indian side regularly so the even the drops of water coming from that side will be mostly urine of chinese and the poor farmers will think it is raining on them until their land gets spoiled.

早先时候，中国表示中国没在西藏修水坝，5年后的现在又改口说修了水坝对下游也没影响，多么有说服力啊修水坝的目的就是控制水流，现在中国人发明了一种新理论，证明他们造的水坝不会对水流有影响，多么伟大的发明啊。

Themotion equations of a bubble near a plane wall have been established with the lift forceand wall effects on the drag force taken into consideration.

我们在全面考虑壁面对空泡运动粘性阻力和升力影响的基础上，建立了空泡在近壁区内的运动方程，计算结果表明由于壁面的存在将阻滞空泡沿水流方向和垂直水流方向上的运动，即有滞留空泡在空化形成点，减缓空泡逸离空泡发生区的作用。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

本文介绍了平面二维水流二维模型研究进展，对河道历史演变概述，通过最新原型观测资料对河道近期主泓线、断面、洲滩、河床冲淤、码头附近冲刷坑等进行详细分析，总结近期河道演变规律，并参考有关文献，对三峡建成后河道演变趋势进行预测；建立了平面二维水流模型，并根据最新资料对模型进行率定和验证，采用模型对几种工况组合进行壅水和流速计算；采用国际上广泛应用的Geo-Slope滑坡稳定分析程序对几种工况条件下工程断典型断面岸坡进行稳定性计算；最后总结工程建设对洪水位、流速、河势、堤防及防洪抢险等方面进行综合评价，得出码头建设对行洪影响较小的结论。

Model experimental studies indicating that when the base slope of spillways changes within the range of 40 degrees to 60 degrees,the water-wing nearly exists in the whole nappe flow ,even continuing to the transition flow.

模型试验表明：当斜坡角度为40°～60°时，水翅存在于几乎整个跌落水流范围内，甚至持续到过渡水流；随着溢洪道底坡的增大，水翅存在的流量变化范围增大、高度增加；随着台阶尺寸的减小，水翅高度降低，所存在的流量变化范围缩小。

Revetments are not only the important engineering measures to protect the riverside from washing out , but also the important transitional regions for exchange of substance , energy , and information between river ecological system and land ecological system .

在河道治理项目中，护岸工程是保护岸边土地，使河岸免遭水流冲刷破坏并稳固河势的一种重要水利工程措施，同时，河岸作为河流自然生态系统中的重要组成部分，是从河道水流环境到陆地环境的过渡。

The water current fuses rock and the mineral quality in the sediment on the other hand, precipitating the mineral quality of excess in water down or becoming crystal on the other hand, along with water current would gradually the 渗 enter to cover up in the bone in the sediment, filling to fill dental cavity and skeleton the organic quality leaves after ising putrefied of space.

水流一方面溶解岩石和泥沙内的矿物质，另一方面将水中过剩的矿物质沉淀下来或成为晶体，随着水流会逐渐渗进埋在泥沙中的骨内，填补牙齿和骨骼有机质腐烂后留下的空间。

In this paper a numerical method—implicit method of finite differences of tidal flow and salinity equations is presented to calculate instantancous salinity in the water taken from the tidal estuary of well-mixed type.

强混合型；无条件稳定；分布状况；计算方法；钱塘江河口；含盐度；潮汐水流；本文介绍一种强混合型河口取水的瞬时含盐度计算方法——潮汐水流和含盐度方程的隐式差分方法。

For example, the irrigation water should reach the end of the rows in two hours out of an eight hour irrigation period or three hours out of a twelve-hour period.

总灌水时间为8小时，灌溉水流应在2小时内到达尾沟；总灌溉时间为12小时，灌溉水流应在3小时内流到尾沟。

In the model, base on the trapping force exerted by the line trap and the water-dragging-force exerted by the flowing water on the bead, the separation of beads is determined.

接著在理论模型上，藉由线形图案作用在不同微粒子的捕捉力以及水流推动微粒子的水流黏滞力，决定细胞之间的分离距离。
