Regional development occupies large land, develops lots of contents, relates to multifields including industry, construction, business and civicism, so it is necessary to identify its influence on nature environment such as air, groundwater quality, surface water quality and hydrological condition, sound, soil, plants, topographty and social environment such as population, traffic, economic structure. The countermeasures of carring through circular economy, controlling pollution sources, planning industrial structure scientifically, distributing reasonably, implementing cleaner production and total quantity control should be taken to promote regional sustainable development.

区域开发具有较大的不确定性，并且占地面积大、开发的内容广、性质复杂、建设周期长，通常的区域开发都有可能涉及到工业、城建、商业、人居、市政等多个领域的开发活动，所以区域开发必须结合区域开发的特征，准确识别其可能对区域内及其周边的空气环境、地下水质量、地表水水质及水文条件、声环境、土壤、植被、地形地貌等自然环境和人口、交通、经济结构等社会环境等产生的影响，并采取发展循环经济，减少污染生成的源头控制措施；科学规划产业结构，合理布局的预防性措施；源内达标、区域集中控制的污染治理措施；实施清洁生产、总量控制，推进区域环境与经济的持续发展。

So the Reverse Construction Method is the designing of execution and construction, these two facts must be combined very closely. Diaphragm wall have three effects in the Reverse Construction Method, it can countercheck soil, compose the construction and countercheck water.

地下连续墙和立柱，既是施工过程中的临时支护体系，同时又要作为地下结构的永久结构体系，因此逆作法设计不仅是施工设计同时也是结构设计，两者必须紧密结合。

As a part of "Outstanding Young Researcher project- Water Erosion Predicting model", the purpose of this study is to do research on the method for estimating Cover and Management Factor in China, to evaluate the effects of crop cover in different stages by estimating soil loss ratio of individual crop stage period, and to compare the effects of different land use patterns by their average annual value of C factor.

本研究作为杰出青年基金项目《土壤水蚀预报模型研究》的一部分，目的在于探讨我国覆盖与管理因子的计算方法，估计不同耕作制度下农地多年平均C值；通过估计不同农作期土壤流失率评价作物发育不同时期对土壤侵蚀的作用；通过估计多年平均覆盖与田间管理因子分析不同土地利用方式的水土保持效益。

It is shown that the shear strength of expansive soil decreases with increasing number of cycles and finally reaches to a constant state. The value and cyclic number of the constant state reduce with increase of amplitude of variation of water content.

研究结果表明：膨胀土抗剪强度随干湿循环次数增加而衰减，最终趋于稳定，强度稳定值与稳定时所需循环次数均随含水率变化幅度的增加而减小。

Electric trains have many advantages over those drawn steam engines. There is no smoke to soil the passengers, clothes and the cushions in the train. Because they carry no heavy loads of coal and water, these trains can start and stop with less waste of power. In a station they are silent: there is no steam to produce noise to deafen the passengers.

电气火车比蒸汽火车有许多优点：没有烟来弄脏乘客的衣服和车上的座垫；因为它们没有很重的煤和水的负荷，这种火车不用多少能量就能启动或者停止；在车站时它们很安静，因为没有蒸气发出噪音使乘客震耳欲聋。

The study indicates that the frost heaving character of the meal sand is decimus of silt clays. And its frost heaving quotiety is seldom influenced by the different freezing end temperature and water content. Thus the surroundings influence is in the small area when the artificial freezing method is used in sand and no-stickiness soil.

研究结果表明粉砂冻胀率是淤泥质粘土冻胀率的十分之一，冷端温度、含水量两个因素变化对其冻胀率几乎不产生影响，因此在砂性等无粘性土中应用冻结法对周围环境危害较小。

In this paper, some influencing factors for fine sediment flocculation and deflocculation, such as the type and concentration of electrolyte, mineral composition, organic matter content, soil pore fluid pH and water turbulence, are reviewed.

文章概述了影响细颗粒泥沙絮凝-分散的几种主要因素——电解质种类及其浓度，矿物组成，有机质含量，pH值以及水流紊动等

There are many kinds of salts in gound water, salt lakes and salty soil in China's western region, and deicer salts have effects on frost resistance and corrosion resistance of cement concrete or corrosion resistance of steel bar in reinforced concete.

我国西部地区地下水、湖水中以及土壤中含有多种盐类，道路除冰盐对混凝土的抗冻性以及耐腐蚀性以及钢筋锈蚀有很大的影响，而混凝土年平均经受的冻融次数对混凝土结构设计具有重要意义。
