河床

The water resources change is a leading factor in the vegetation degeneration there; The swamp vegetation was based on the background of large-scale lakes and rivers; the halophyte meadow was based on the background of dry lakes and riverside, and desert vegetation was based on the background of desert; desert vegetation was based on the background of desert at present.

水资源的变化是决定当地植被退化的主导因子，在大面积湖泊、河流背景上是沼泽植被，在干涸湖泊、河床背景上的是盐生草甸植被，在沙质荒漠背景上的是荒漠植被。

Shortly after, Alpha and Bravo began their advance toward Herrick's lost platoon from the creek bed.

在这之后不久，Alpha连和Bravo连开始从了小湾河床向被包围的Herrick排推进。

Devney's platoon led approximately 100 yards west of the creek bed, with Herrick's men to his rear and right flank.

Devney的排来到小湾河床西边大约100码左右的地方，Herrick的人在Devney的后方和右侧面协同推进。

We shall utilize comprehensively the theories and practices of hydrometry, ecology, environmental science and systematic engineering to divide the upper reaches of Li River into five sub-systems such as headwater forests, riverbed, changing volume in wet and/or dry seasons, faculties for retaining water and controlling flood, and the bearing capacity of the water resources so as to construct a systemic analysis framework for the research of this area.

综合运用水文学、生态学、环境科学、系统工程学等理论和方法，将漓江上游流域划分出水源林、河床、丰枯期水量变化、蓄水减洪设施、水资源承载力五个子系统，构建起漓江上游水资源的系统分析框架。

Every fact which occurs in the bed, on the banks or in the air over it; the fishes, and their spawning and nests, their manners, their food; the shad-flies which fill the air on a certain evening once a year, and which are snapped at by the fishes so ravenously that many of these die of repletion; the conical heaps of small stones on the river-shallows, the huge nests of small fishes, one of which will sometimes overfill a cart; the birds which frequent the stream, heron, duck, sheldrake, loon, osprey; the snake, muskrat, otter, woodchuck and fox, on the banks; the turtle, frog, hyla and cricket, which make the banks vocal, were all known to him, and, as it were, townsmen and fellow creatures; so that he felt an absurdity or violence in any narrative of one of these by itself apart, and still more of its dimensions on an inch-rule, or in the exhibition of its skeleton, or the specimen of a squirrel or a bird in brandy.

河床上的河岸上的每一个变化，以及空气变化；河中的鱼类及产卵期和汇聚处，它们的行为和食物；河鲱蝇在一年的某天夜里充斥了空气被河中的鱼疯狂吞吃，以至于好多鱼暴胀而亡；在河的浅水湾的一些圆锥形石堆，其中有一个有时能装满一手推车，----这些石堆是一些小鱼的巨巢；那些经常巡游河中的水鸟，苍鹭、鸭子、翘鼻麻鸭、潜水鸟、鱼鹰；河岸的蛇、麝鼠、水獭、啄木鸟和狐狸；还有那使得岸边有了活力的龟、青蛙、雨蛙和蟋蟀----这一切他都熟悉，就像它们是镇子上的人和同类；于是他会感到强烈的荒谬和粗暴在看到任何关于它们的孤零零的描述，以及把它们丰富的内涵压缩在一个方寸的纸上，或展览它们的骨骼，或把一只雀儿和鸟类泡在白兰地酒中保存。

There may be a deep cliff in the bed of a stream.

在一条河床上可能有一个陡峭的悬崖。

This whole process leaves the stones in rubble, and heaps in valleys and sometimes in riverbeds where two bodies of water come together.

这整个过程中留下的石头瓦砾，在山谷和堆在河床上，有时在两个机构的水走到一起。

Incongruously these measures usually are only temporary, since a riverbed is subject to permanent changes.

不适当的是，这些措施通常仅仅是暂时的，因为河床处于永久的变化中。

It's a splendorous landscape, dynamic and rich, tumultuous and delicate, encompassing 2.8 million acres of volcanic mountains and forest and tundra and river bottoms as well as more than 700 brown bears, thickets of Siberian dwarf pine and relict "graceful" fir left in the wake of Pleistocene glaciers, a major rookery of Steller sea lions on the coast, a population of kokanee salmon in Kronotskoye Lake, along with sea-run salmon and steelhead in the rivers, eagles and gyrfalcons and wolverines and many other species—terrain altogether too good to be a mere destination.

这里有着宏伟的地貌，生气勃勃、富丽堂皇，喧嚣热闹、精美雅致，280万英亩的区域包含了火山山脉、森林、苔原、河床以及超过700只的棕熊、茂密的偃松（可为熊提供可食用的坚果）和更新世冰河后期遗留下来的优美的冷杉，沿岸是一个主要的白令海狮栖息地，库页湖中生长着红大麻哈鱼群体，陪伴着河里的洄游大麻哈鱼和虹鳟，还有鹰、矛隼、狼獾和其它物种——总之，把它作为一个纯粹的栖息地带再好不过了。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
