Therefore,it is meaningful to research the Numerical method of diffusion equation for suspended sediment.

在天然河道中，悬移质泥沙运动与河床的冲刷和淤积、取水排水等实际生产问题有密切联系。

A important conclusion is that fluvial-lacustrine, karst, diluvial, colluvial, glacial and outwash deposits, which formed between early Pleistocene and early middle-Pleistocene, have high cement degree, low permeability, high intensity, low deformation, and good engineering properties, but modern riverbed phase deposits, which formed in between late middle-Pleistocene and Holocene, are loose, highly permeable, weak, highly deformable and have bad engineer characteristics, so they are susceptive to differential settlement, piping, drafting, liquefaction problems.

得出早更新世—中更新世早期河湖相沉积、岩溶沉积、洪积、崩坡积、冰碛和冰水沉积密实度高，胶结较好，透水性差，强度高，变形小，工程性质较好，而中更新世晚期—全新世现代河床沉积较松散，渗透性高，强度较低，变形较大，易发生差异沉降、管涌、流土、地震液化等工程地质问题的重要结论。

Zambia—The 355-foot (108 meter) drop of Victoria Falls just inches away, a swimmer stands at the lip of a hidden pool—an eight-foot-deep (2 meter) divot in the riverbed rock—accessible only when the Zambezi River runs low.

赞比亚的355英尺（108米）的维多利亚瀑布下降只是一步之遥，一个游泳站在河床岩石中的一个隐藏的嘴唇池八英尺深（2米）草皮，只有当访问赞比西河河耗尽。

These areas are not just attractive for their beauty, they're also critical transition zones from marine to terrestrial and freshwater habitats, and are the sites of nurseries for a host of marine species in the form of salt marshes and eelgrass beds.

因为这些地区不仅仅风光秀丽同时还是海洋到陆地和淡水栖息地的关键过渡区。同时这些地区的河床和盐沼是海洋的主人——各类海洋生物形成的摇篮。

Across the road would be new rail fences, inclosing fat cattle and blooded horses, and the red earth that rolled down the hillside to the rich river bottom land would gleam white as eiderdown in the sun—cotton; acres and acres of cotton!

大路对面将有一道新的栅栏把肥壮的牲口和纯种马圈起来，而那片从山腰伸到肥沃的河床的红土地，将像凫绒被似的在阳光下闪耀银光----棉花，大片大片的棉花啊！

坎比亚索在河床的前途将是不完美的。

When the Ganges comes down, it might be expected to wash the excrescence back into the soil.

流经这里的恒河似乎随时可能把这块多余的地方冲回到河床底下去。

Now if I have to go away, I'll do it quietly, I'll be going as a champion, said Fernandez.

现在，我要对俱乐部说离开了，并且很快就走，我将会像在河床一样收获更多的荣誉。

River Plate star Augusto Fernandez warns Lazio they are his number one choice, but time is running out.

With VC++ as programming language, a dynamic visualization system of flow field and river bed change process is developed based on Tecplot, an excellent graphic platform.

本文采用可视化技术，利用功能强大的编程工具VC++在优秀的图形软件平台Tecplot上进行二次开发，建立了流场及河床冲淤变形的动态演示系统，该系统功能齐备，通用性强，操作灵活，使用方便。

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。
