In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.

为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况，我们于2004～2005年对全市污灌区的土壤和小麦进行了采样，在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上，本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平，主要的污染因子是Cd和Zn，同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价；然后分析了重金属在小麦不同部位的含量与富集能力，评价了污灌区旱地作物小麦普遍遭受了Cd的污染，只有个别样点遭受了Zn的污染；最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析，由于土壤类型是定性变量，本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型，经复相关系数检验，污灌区主要的污染因子Cd和Zn的预测精度最高，模型可以成立。

If an external variable declaration does not include a declared type, the type and a matching value must be provided by the external environment at evaluation time.

如果一个外部变量声明不包含一个已声明类型，类型和匹配的值必须由外部环境在求值时提供。

If an external variable declaration also includes a declared type, the value provided by the external environment must match the declared type, using the matching rules in 2.4.4 SequenceType Matching (see 2.2.5 Consistency Constraints ).

如果外部变量声明也包含一个声明的类型，则由外部环境声明提供的值必须与声明的类型一致，此处应用2.4.4 SequenceType Matching中的匹配规则（参见2.2.5 Consistency Constraints）。

We should take the economic system and the system of natural resources as a whole, which make a country to pay attention to the protection and the sustainable use of natural resources. The finiteness of natural resources let us think the sustainable development of economy.

从经济角度而言，资源永远是稀缺的有价的，它是生产函数的基本变量，自然资源的禀赋及供给情况决定了一个国家的经济增长路径，将经济系统和环境资源系统作为一个整体来考虑，就要求一个国家在发展经济的同时注重本国资源的保护和可持续利用。

The purpose of this paper was to account for the institution variable and institution innovation of implementing the sustainable development stratagem when the time was globalism .

本文的目的在于探讨在环境问题全球化和全球经济一体化的情况下可持续发展战略实践中的制度变量和制度创新问题。

Culture and economic growth have immanent connection, be economic growth inside unripe variable and environmental support.

文化与经济增长具有内在的联系，是经济增长的内生变量和环境支持。

Under actual production environment, we may see some information frequently such as due data and process time which are described imprecisely, and scheduler often take some fuzzy information into account during the process of scheduling.

在实际的生产环境下，我们经常可看到一些信息，例如交货期和加工时间，这些变量的描述是不精确的，而且调度人员在调度过程中也经常考虑一些模糊的信息。

This thesis attempts to account for the success of foreign language schools from several important variables that primarily influence the outcome of language education in the frame of social constructionism and interactionism.

本文拟根据社会构建理论和社会互动理论从教师，学生，教材，教法，环境和评估等影响语言教学的几个重要变量来分析并解释外国语学校英语教育的成功之道，'o 最后，本文一方面提出了一些关于中学英语教育的建议供同行借鉴并为《英语课程标准》在全国的实施提供一些可供参考的经验。

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.
