水流

He rushed across the plain like a winter torrent that has burst its barrier in full flood; no dykes, no walls of fruitful vineyards can embank it when it is swollen with rain from heaven, but in a moment it comes tearing onward, and lays many a field waste that many a strong man hand has reclaimed- even so were the dense phalanxes of the Trojans driven in rout by the son of Tydeus, and many though they were, they dared not abide his onslaught.

泛滥的河流，汹涌的水头冲垮了堤坝，坚固的河堤已挡不住水流的冲击，那一道道卫墙，防护着果实累累的葡萄园，亦已刹不住它的势头，宙斯的暴雨汇成滚滚的洪流，翻涌升腾，荡毁了一处处精耕细作的田园。就像这样，图丢斯之子打散了多支特洛伊人的队伍；敌方尽管人多，但却挡不住他的进攻。

The constructed wetland was a good new ecological method for treating eutropic lakes water with abundant algae.

藻类的去除主要发生在湿地水流方向的前几层，而系统其他层对藻类只有微弱的去除效果。

After digestion, any remaining material is egested from the anus and passes out with the water flowing out the excurrent siphon

经过消化之后，任何残留的物质都通过肛门排遗，并随水流流到出水管外。

Based on analysis of the current state of the flow pattern modeling abroad and at home, explains the meaning of the mathematical simulation of the flows in the valve.(2) Comparing flow simulation data of jet pump with its experimental one, the feasibility and reliability of FLUENT used for flow simulation are proved.(3) Based on the characteristic of valves, the fluid field analysis of specific ring-spray type flow-adjustable is finished. The valve structure is optimized to meet the need, which makes it have such advantages:(1)smaller vortex area and faintish vortex intensity, so the vibration of vortex is controlled effectively;(2)the pressure is distributed more equality, the transition area is larger.

论文的主要内容包括：(1)简述了阀门研究的现状与发展，在分析与总结国内外流体流动模拟研究的基础上，探讨开展阀门内水流运动数值模拟的意义；(2)对特定型号的射流泵进行了内部流场的数值模拟研究，并与实验数据相比较，验证了应用Fluent进行数值模拟的可行性和可靠性；(3)针对调流阀的特点，对特大口径环喷式流量调节阀进行流场计算，其设计指导思想如下： 1、控制旋涡，减小旋涡区，减小涡的强度； 2、控制压力分布，使阀体受力更均匀，改善局部应力状态，提高阀门使用的安全性； 3、最小绝对压力高于水的汽化压力，不产生汽蚀。

本发明涉及一种电水箱，特别涉及一种不浪费热水管中存留的冷水直接为用户提供热水的电水箱热水直供装置，它包括微控制器、键盘电路、显示电路、控制驱动电路、信号放大、整形电路、A/D转换电路、水流开关S、温度传感器W1、温度传感器W2、温度传感器W3、水位传感器H1、电控阀Y1、三通电控阀Y2、电控阀Y3、水泵M和加热带。

Firstly, pressure, enthalpy, temperature and velocity of pure water at different location of hydrothermal circulation system are described. Density and viscosity of fluid are calculated from temperature and pressure using properties of pure water. Secondly, influences of formational anisotropy and crack zone on hydrothermal circulation are analyzed.

首先讨论了热液循环系统不同部位的压力、焓、温度、水流的密度、粘度及流动速度等参数的特征，其次分析了地层非均质性、裂缝带的存在对热液循环流场的影响，最后分别模拟了近临界状态及侵入体存在情况下的热液循环。

Here the air was clear and light, and the river Froom rushed as fast as the shadow of a cloud.

这儿的空气清新怡人，福鲁姆河水流湍急，就像一片白云的影子匆匆掠过。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.

低位泥炭沼泽由于潜水位较高，水流对泥炭沼泽表面的改造和冲刷作用较强，形成的煤层具有较高的凝胶化指数和地下水流动指数，并且与精煤产率呈负相关，煤中粘土矿物和黄铁矿难以洗选；高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数，泥炭积累速度较快，其精煤的产率较高。

If you come up the waves that flow glidingly on the rocks and become a fall when they meet a small curve, Yeonwhadam show up.

沿着时而快速流过岩石、时而形成小小瀑布的水流逆行而上，即可到达莲花潭。

May: let you guss something .A cup falls on the floor but no water spills out .Why ?

妹妹：让你猜猜，如果一个杯子掉在地上但是没有水流出来，这是为什么呀？

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。
