河流

Based on analysis of the factors affecting subgrade local scour along the river such as condition of stream,condition of bed form,geometric boundary condition of river,water depth and speed of every section,scour depth of parapet,the progress of scour and the form of stream near parapet were observed through the way of field model experiment.

在对沿河路基局部冲刷影响因素如水流条件、河床沙条件和河流几何边界条件等进行分析的基础上，通过野外模型试验，观测了河流各断面的水深、流速、护墙的冲刷深度和冲刷的发展过程及护墙附近的水流形态。

This time we samplinged and analyzed the river-water and bottom sediment in the goldfield of Shaanxi Tongguan which is the representative goldfield in China. We not only evaluated the situation of heavy metals pollution arose by mining, but also analyzed the distribution regularity about heavy metals pollution in the space and the correlation among heavy metals.

本次对我国的典型金矿区—陕西潼关金矿区河流中的河水和底泥进行采样分析，评价采矿导致的该地区重金属污染状况，分析重金属污染的空间分布特点和几种重金属之间的相关性，进一步提出金矿区河流重金属污染的治理方案。

In the channel regulating work, regulating structures such as groyne, longitudinal dam are used to change water depth, water velocity and water surface slope of the channel.

航道整治工程中，常采用修建整治建筑物如丁坝、顺坝等来改善河流的水深、流速、水面比降，使河流达到通航要求。

In this world here, you may not find the mountains and rivers, but the handicraftsman and his works will bring the taste of nature to you

而这里，虽然没有山川，没有河流，但却有一位来自山川河流的木匠，和一个木匠的世界。。。。。。。

The results are listed as follows:(1) In peneplain with plenty water-resource, hexagonal spatial structure of urban system can be formed. Due to differential competed function of central places, the hexagonal system is distorted. The result is that the area covered is decr eased and the girth is unchanged——but every border is usually unequal;(2) A pattern of pentagonal system evolves from hexagonal system controlled by a river;(3) A pattern of quadrilateral develops from hexagonal system under two parallel rivers;(4) The equal distance distribution of central places in narrow geographic space has its special reasons. The results are very important for understanding urban's formation and development and urban plan in Huang-Huai-Hai plain.

本文通过自然地理因素中水文、地形这两个重要要素对城镇体系空间结构形成的影响，分析了华北平原区在不同要素影响下的城镇体系空间结构样式：①在水源充足的准"均质"河北冲积平原上，基本满足六边形形成条件，但由于周边中心地发展竞争力不同，故使得正六边形发生畸变——覆盖面积减小而周长却保持不变；②构建了在一条河流影响下的六边形网络结构朝五边形网络演变的模型；③构建了在平行状河流作用下六边形网络向四边形网络演替的模式；④指出了在水源充足的狭长地理空间，城镇体系空间结构发育成等间距的现象与原因。

Secondly, owing to high sediment load, Yellow River demands more water as "the fundamental water flow of maintaining its own life" than other major rivers in the world.

其次，与其他河流相比，多沙的特点使得黄河需要更多的"维护河流自身生命的基本流量"。

Scoyenia ichnofacies widely occurs in flood plains and the transitional belts of rivers and lakes, Termitichnus ichnofacies owns features of continental environment, Rusophycus ichnofacies made its appearance in river channel and levee sub-environments of relative high energy, Arenicolites ichnofacies colonized on the surface of hummocky sandstones of storm deposits.

Scoyenia遗迹相广泛发育在洪泛平原、冲积平原以及河流与湖泊的过渡地带，Termitichnus遗迹相是陆地沉积环境的特征，Rusophycus遗迹相出现在河流沉积环境河道、堤岸等能量较高的亚环境。Arenicolites遗迹相在开阔湖风暴沉积的丘状砂岩层面上拓殖，主要由机会分子构成。

On the premise of protecting river hydrobiology habitat, ecological water demand in mountainous rivers was studied.

主要从保护河流水生生物栖息地出发，探讨山区河流生态需水量问题。

In almost all of the disputes that have been resolved, however, particularly on arid or exotic streams, the paradigms used for negotiations have not been 'rights-based' at all — neither on relative hydrography nor specifically on chronology of use — but rather 'needs-based.

在几乎所有的被解决的水争端中，尤其是那些干旱地区或异常河流的情况中，谈判的范式根本不是"权利本位"——既不是水文学的也不是关于河流时段利用方面的——而是"需要本位"。

This paper discuss the pollution of Xingyun Lake rivers ,By the use of ponds space, we get the corresponding engineering measures to purify water, to reduce the load of pollutants which into the lake, to improve the water quality of estuarine waters, Finally we can prevention and cure the infectant water let into the lake.

本文针对星云湖入湖河流存在的污染问题，利用鱼塘空间，提出相应工程措施，以净化水质，降低入湖污染物负荷，有效改善河口区水域水质，实现入湖河流水污染防治的目标。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
