河流

"Boundaries between states or shires, they were crossed by fords which became the sites of towns, or by bridges which were often points of battle."

作为州或郡的分界线，河流上的浅滩成为城镇的所在地，横跨河流上的桥梁则是兵家必争之地。

At the same time, surveying the borderlines between sea and river was carried out across-the-board in the whole province: 95 out of 118 ocean outfalls have been delimited, which makes the marine environmental administrative zones clearer.

同时，全省河海划界工作也全面展开，全省118条入海河流已完成了95条的入海河流的河海划界工作，进一步明确了各行政区海洋环境管理的区域范围。

To be honest, I had been trying to imagine that I was walking along a long, navy blue river alone where rainbow-colored fish was living in. Suddenly, I stopped walking.

老实说，我曾经想象自己独自一人沿着一条深蓝色的长长的河流漫步，河流里住着许多七彩鱼。

较全面揭示冲积性河流阻力关系的H·A·爱因斯坦，他根据床面泥沙的运动影响与水流强度之间的关系及水体能量的分配、传递方式，把冲积性河流的阻力分成以下几个单元：沙粒阻力、沙垅阻力、河岸阻力、河槽形态阻力等，并通过水槽实验和野外实测资料的分析验证，提出了明渠水流阻力的可加性原理[1-2]———水流总阻力等

Particular landform of Tacheng Region allows water vapor from the west, so as to form many medium-and small-sized rivers. The seasonal snow covers the hills. During the snow-melting season in spring, the rivers have the character of spring flood, which makes uneven distribution of annual runoff and results in a disadvantaged allocation of water resources.

塔城地区独特的地形为西来水汽的输送提供了条件，从而形成了众多中小河流，而中低山带季节性积雪的消融又使河流呈现出春汛的特点，使得径流年内分配不均，对塔城地区水资源配置极为不利，开展径流量的预测研究，将为水资源的优化配置提供科学的理论基础。

As long as it keeps itself in the middle of rivers, drifting day and night, it is possible for him to reach the sea.

因此，也只有尽量的、小心的将自己保持在河流中央，顺著河流日夜不停的走，如此才有可能顺利而完整的漂流到大海中去。

Born in the icy headwaters of rivers on the east coast of North America, Britain, Iceland, Ireland, Poland, Portugal, Russia, Scandinavia and Spain, baby salmon, or parr, swim far out to sea to fatten up on herring and sprat.

鲑鱼繁衍于冰雪覆盖的河流源头，这些河流分布在北美东海岸，不列颠，冰岛，爱尔兰，波兰，葡萄牙，俄罗斯，斯堪地纳维亚半岛，以及西班牙。鲑鱼幼仔，或更大点的个体，就从远离大海的河源溯水而来，靠捕食鲱鱼以及鲱类小海鱼得以成长。

Reports and data provided include: downloadable annotated reports with data relating to the water quality (including trace metal concentrations) of the Forth Estuary between the years 1980-99, water quality standards for various coastal stretches in East Scotland, water quality classification schemes and resultant data (excellent - poor) for rivers, estuaries and coastal waters, bathing water data (1998 - 2001), SEPA indicator measurements for surface water quality, and a national archive of water quality data taken from 230 sites around Scotland which is used to estimate the river-borne input of selected contaminants to the sea and investigate long-term trends in main determinands.

其中包括：可下载报告全文，并带有1980-1999年Forth河口水质的相关数据，东苏格兰海岸不同的水质标准，水质分类方案及河流、河口、沿海、浴水的合成数据（1998-2001年），苏格兰环境保护机构的地表水质指示剂测定法和国家水质档案资料（水样取自苏格兰各地230个点位，常用于估计河流承受的污染物输入和调查长期趋势）。

Rapids are created when rivers are on a steep gradient, making the water flow very fast, when the flow is constricted into a narrower channel, or where an obstruction such as a boulder interrupts the river, causing eddies and swirling currents.

当河流的坡度陡斜造成水流变快的时候，当水流被挤入更为狭窄的河道的时候，或是在河流被巨石之类的障碍物阻隔从而引起旋涡和涡流的地方，就会形成急流。

The results show that:①The vegetable garden soils are developed from the alluvial deposit in the alluvial terrance and quarternary red clay in the hilly valley and are located in the lower smooth terrain.

结果表明：①供试6大基地的土壤主要分布在河流两岸的河谷阶地和河漫滩以及红壤丘岗谷地，由河流沉积物和第四纪红色粘土发育而成。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
