土层

Under both furrow and drip irrigation, potato roots were mainly concentrated in 0～40cm depth of soil layer.

沟灌和滴灌条件下，马铃薯的根系均主要集中在0～40cm土层深度范围内。

Backed by the county Ziwuling Weiwei, small environment humid climate, natural vegetation in good soil plateau surface deep, high organic matter content, non-industrial and mining pollution, the production of the fruit tose yan a big, rich flavor, high sugar content, hardness, resistance and the renowned Quartet storage. Qinguan Apple in 1997, the National Rural fruit fruit variety evaluation at the won the "Huludao Cup" Gold; Fuji apple 1996,1997, Gansu Province, respectively the second high-quality fruit products Thelin Evaluation Council, the first fruit products exhibition Gold rendezvous. 2004, 2005 respectively "Honey Longde card" Trade Marks Registry and the National Green Food Certification.

本县背靠巍巍子午岭，小环境气候湿润，境内自然植被良好，塬面土层深厚，有机质含量高，无工矿企业污染，生产的果品以个大色艳、香味浓郁、含糖量高、硬度大、耐贮藏而享誉四方。1997年秦冠苹果在全国果乡果品综艺品评会上荣获&葫芦岛杯&金奖；红富士苹果1996、1997年分别获得甘肃省第二届名优特林果产品鉴评会、首届林果产品展交会金奖。2004年、2005年分别获得了&陇蜜牌&商标注册和国家绿色食品认证。

In this paper were investigated the method of drainage and boring technology through the stratum of quick sand ,silt soil,rock and Karst by asing the method hand-dug pile under condition of complex geologic foundation.

本文就人工挖孔灌注桩在复杂地基条件下的排水施工方法，穿越流砂、淤泥质土层，岩层和岩溶地基的人工成孔施工技术作了有益的探讨。

Random boundary ; seismic response of soil layer ; wave impedance ratio

随机边界；土层地震反应；波阻抗比

Based on these solutions, the dynamic responses of integral pile and pile with various impedances are investigated.

研究表明，不仅桩身变阻抗特性会对桩的动力响应产生影响，土层参数的变化也会产生相应的影响。

The results indicate that soil factors within the range of 0-35cm influents intensively the distribution of local community.

影响群落分布的土壤厚度约为35cm，即植物群落分布与0～35cm深度土层的土壤理化性质相关性最大。

The second method is allowed for complex geological conditions (inclined occurrence of the soil layers, the presence of karsts, frozen soil lenses, and so on) and is based on the use of more complex calculation schemes which also account for the inertia properties of the soil base.

第二种方法是让复杂的地质条件(倾向发生的土层中，在场的溶洞，冻土镜片，等)，以及基于使用更复杂的计算方案，其中还占惯性土壤性质的基地。

The characters of karsts soil are four:(1) soil layer is thin and the soil is barren;(2) the soil is not continuously distribution and separated by the stone-teeth;(3) water and soil resources are separated;(4) slopping field is more, the flat is few.

岩溶区土壤资源的特征是：①成土速率慢，土层薄，土壤贫瘠；②土被不连续，多被石芽所间隔；③水土资源分离；④坡地多、平地少。

Because of its serious pollution to the circumjacent environment and substrate of the landfill, the long-term maintenance of pollution, and the secondary pollution, it is an urgent problem to collect and treat the landfill leachates effectively in city environments.

垃圾渗滤液是一种危害较大的高浓度有机废水，对周边环境及填埋场场底土层污染严重，且污染持续时间长，容易造成严重的二次污染问题，因而对渗滤液进行有效的收集和处理已成为城市环境中急待解决的问题。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.

研究首先建立了基于GIS的地统计学采样和分析方法的步骤，然后着重分析了土壤铜镉复合污染的空间变异特征和影响因素，发现研究区土壤铜镉复合污染为点源污染类型，铜在土壤中具有明显的表聚性，而镉容易迁移，在0-60cm的土层中均形成污染，同时土壤的复合污染已经在水稻籽粒中引起污染物超过食品食用标准。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
