Or again, note the meanderings of some purling rill as it babbles on its way, tho' quarrelling with the stony obstacles, to the tumbling waters of Neptune's blue domain,'mid mossy banks, fanned by gentlest zephyrs, played on by the glorious sunlight or 'neath the shadows cast o'er its pensive bosom by the overarching leafage of the giants of the forest .

113再则，请注意那打着漩涡蜿蜒曲折地哗哗淌去的泪泪溪流与拦住去路的岩石搏斗，在习习西风轻拂下，冲向海神所支配的波涛汹涌的蔚蓝领国；沿途，水面上荡漾着灿烂的阳光，两边的堤岸爬满青苔，森林中的巨树那架成拱形的繁叶，将荫影投射于溪流那忧郁多思的胸脯上。

The main results can beexpressed as follows:(1)Based on πtheory, some affected factors about wave forces are given, and therelation between affected factors and wave forces is analysised by experimentalresults.(2) The distribution of wave press at representative time and reflection nature aregiven and their variety charactes are discussed by experimental results.(3)By comparing the wave forces of quarter-circular breakwater and semi-circularbreakwater under the same wave conditions,some approximately wave forcesexpressions of quarter-circular breakwater are given.(4)Based on VOF method to trace water free surface,solve numerical value ofRANS equation,and get the distributions of flow field and wave press ofquarter-circular breakwater at the same time during one period,the mechanism ofwave force is also discussed elementarily.(5) Based on the result that RANS equation of numerical simulation agree wellwith experimental results,a new approach to study hydraulic natures of quarter-circular breakwater is provided.

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

Cation group has the capability of charge neutrality and this would make oily wastewater demulsify and remove oil easily. Hydrophobic group would improve hydrophobic-oleophilic nature of the oil granule. Simultaneously, wetting reversed agent would change wetting performance of oil granule, enhance conglutination capability between air bubble and oil granule. And Frother would form bigger foam layer on the water, so it could prevnt granule with air bubble from rolling downward.Using the hydrophobic polymeric flocculant as one of ingredients for flotation agent formula, the flotation agent has good treatment effect.

浮选剂配方中的疏水性高分子絮凝剂分子链上带有的阳离子基团起到电中和作用，使含油污水易于破乳除油，而疏水基团能增强颗粒的疏水性能；润湿反转剂能改变颗粒的润湿性，增强气泡与颗粒的粘附能力；起泡剂在水面能形成强度较大的泡沫层，起阻止带气絮粒向下翻动的作用。

All this comes as China grapples with a mounting water shortage. Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools. According to official statistics, more than half of China''s major waterways are so polluted that fish are dying or water is unsafe for drinking or irrigation. More than 300 million people -- almost one-quarter of the population -- lack access to clean drinking water, the government says.

所有这些问题都是在中国水资源日益短缺的大背景下出现的在全国许多地方，大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池，大片水面被藻类所覆盖从官方的统计数字看，中国一半以上主要河流的污染程度已经严重到了鱼虾绝迹或河水已无法供饮用和灌溉之用的程度

We were ranged round about a fountain offering hecatombs to the gods upon their holy altars, and there was a fine plane-tree from beneath which there welled a stream of pure water.

在一泓泉流的边沿，一棵挺拔的松树下，清湛的水面闪着烁烁的鳞光，当我们用全盛的牲品在神圣的祭坛上奠祀众神时，一个含意深邃的预兆出现在我们眼前。

A shrimp bouncing slowly across the bottom or falling through the water column is a far better trigger than one just sitting there doing nothing, but don't be surprised if after getting a taste for prepared foods, the lionfish actively grows to recognise and take food whether its falling through the water column, or settled on the bottom (they really can be Hoovers on occasions).

一只到处游动的强壮的小虾比一只呆呆的在那里什么都不做的小虾更有吸引力，但如果驯饵成功后，狮子鱼一旦品尝到并习惯于人们提供的食物的味道时，无论食物是从水面落下还是静静的呆在缸底，都会非常积极地去吃。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
