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。

When I got up and switched on the computer a message from my darling was clearly shown on the screen as expected, and then I refined this dream with some fictive details and told it to her.

而我，生来死往，就像一片云彩，为太阳的升起，宁愿踪影全无，我无怨无悔。

Firstly, those useless to classify texts are filtered according the category document frequency distribution difference of each feature; and then in order to overcome the limitations of TF-IDF weighting formula a novel weighting formula called TF-CDF is presented . Calculate the weight of each feature according to TF-CDF and build the Vector Space Model for the entire corpus. To select significant features, a feature selection approach based on Variable Precision Rough Set is also proposed and implement with some SQL sentences combining the definitions of VPRS with the advantages of SQL sentences.

该文首先根据特征词的类别分布差异进行特征过滤；然后，分析传统的权值公式TF-IDF的缺点，采用改进的权值计算公式简记为TF-CDF，依据TF-CDF公式计算每个特征词的权值，生成文档集的向量空间模型VSM；接着，提出了一种基于可变精度粗糙理论的特征选择进一步选择对分类贡献度大的特征，并用SQL实现。

This theory emerged from those philosophical and logical inquires Russell made in his early stage, when Russell use logical analysis to solve the semantics problem his meaning theory suffered. The foundation of the theory of descriptions is a theory of meaning, as this thesis presents, and its central notion includes two syntax rules. Based on the first order predicates calculus, this theory seems successfully solve some notable semantics problems and then assures Russell's denotation theory.

本文认为，摹状词理论有深刻的哲学渊源，它脱胎于罗素早期的哲学和逻辑研究，直接缘起于罗素想要利用逻辑的分析方法去解决意义指谓论所面临的语义学难题；摹状词理论的基础是它的意义理论，核心是两个句法规则，它基于带等词的一阶谓词演算成功地解决了一些著名的语义学难题，维护了直观的指谓论，从而产生了巨大而深刻的哲学影响。

And I believe this may have been the case with many, who, having, for want of some such means as I employed, found the difficulty of obtaining good and breaking bad habits in other points of vice and virtue, have given up the struggle, and concluded that "a speckled ax is best;" for something, that pretended to be reason, was every now and then suggesting to me that such extreme nicety as I exacted of myself might be a kind of foppery in morals, which, if it were known, would make me ridiculous; that a perfect character might be attended with the inconvenience of being envied and hated; and that a benevolent man should allow a few faults in himself, to keep his friends in countenance.

他们为了缺乏一些什么，和我所用的方法一样，等到得到好习惯和破坏恶习惯的困难，就抛弃了善恶的竞争，而结论说是「一把有几处白光的斧面是最好的斧头」，也可假藉一些理由，因为有些东西时常向我建议说，如自我期许的极端细密也许是道德上的蠢事，而如果他人知道了，会让我成为可笑的人了；而一个完美的人格必将受到嫉妒和憎厌；所以有善心的人必得在身上留一些缺点，以保留他朋友的面子。
