水面

In reservoir design one sometimes meets with submerged structures, such as the underwater retaining wall, the foundation-rested immersed, plate which connects shore to intake-tower, the half-submerged navigation-guiding plate, a strut plate positioned midway in water depth, and also a diversion wall from shore.

在实际工程中，有时遇到某些建筑物是潜没在水中的，如水库水面以下的挡土墙和水库进水塔与岸边连接的撑墙；又有时遇到挡水建筑物与基础脱离，如水库中的导航板；另外还有一些既潜没在水面以下又与基础脱离的建筑，如水中撑板；还有岸边的平板。

A broad expanse of the river was turned to blood;1 in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous;2 in one place a long, slanting mark lay sparkling upon the water; in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced; the shore on our left was densely wooded, and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun.

不远处红光闪成金黄；孤零零的一根原木在河中漂浮而来，呈一线醒目的黑色；河的一处，一条长长的斜影横落在水面上，闪闪烁烁；另一处，水面被翻滚的水波打碎，仿佛蛋白石放射的斑斓色彩；红彩最淡处是一片平静的水面，覆盖着优雅的环形和放射状的波纹，细腻如绘；河左岸是一片浓密的森林，一条长长的崎岖小径划破树林的一片荫翳，闪闪如银；一株光秃秃的枯树高耸于密林之上，仅剩的一杆青枝随风摇曳，像火焰闪耀在阳光洒下的一览无遗的壮美之中。

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。

In view of the national conditions, the medium-small scale naval vessel above water of our navy is mainly displacement type monohull, the displacement type monohull remains the most basic selected type of the naval vessel above water during future quite long period.

鉴于国情，我海军中小型水面舰艇主要是单体排水式船型，在未来相当长一段时间内单体排水式船型仍然是水面舰船的最基本的选型。

The wrigglers' transparent bodies usually float upside-down, breathing through their tails, pulling air from the waters' surface. They feed upon plant-life in the water.Short lifespan, breeding cycle

呈现透明状的孑孓，经常是以倒挂方式在水面下，利用尾端的呼吸管吸取水面上的空气，并且仰赖水里的有机物质维生。

The geology in this part of the Tibetan Plateau is not granite, like the Sierras, but seabed, like our Rockies, so its limestones, dissolving, color the waters emerald or turquoise in a certain light or enhance the mirroring of an azure sky.

青藏高原的这一部分的地质并不是像内华达山脉一样的花岗岩，而是像洛基山脉一样来源于海底大陆架，是石灰石质的。石灰石溶解，使得水面在一定光线下呈现翠绿色或青绿色，倒映在水面的蔚蓝的天空显得更蓝。

They were not the ordinary pyramid-shaped teeth of most sharks.

它眼下就在水面下迅速的游着，高耸的脊鳍象刀子般划破水面，一点也不抖动。

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。
