抽取

This paper introduces a convenient reengineering assistanttool which was developed by the author and other researchers in De Montfort University,UK,and can be used to abstract a specification from a pro-gram(i.e.from source code text to specification source text),and give a case study with RA.

因为程序设计和规约是在更高的抽象层次上，这一层次更简洁或易于理解。从源代码中成功抽取面向语义的规约，将有利于理解，从而有助于对遗留系统进行再工程。从

Methods: The study sample comprised 1 573 35～44 year old and 1 515 65～74 year old Guangdong residents recruited from urban and rural areas through multi stage cluster sampling.

By extracting, transferring and lodging the dispersed data into central DW, water quality can be assessed through OLAP operation on multidimensional data model.

数据仓库系统可以把分散的数据经过抽取、转换，装载进中心数据仓库，建立多维数据模型，利用 OLAP 的分析功能完成各种水质评价工作，更好的辅助决策者决策。

In this sense, multiple remote sensing image fusion is a focus of attention in military remote sensing field.

综合利用多源遥感图像可抽取更具价值的信息，提高感兴趣区域或目标解译的可靠性和准确性。

Three hundred and sixty-nine subjects were recruited from the junior grades of three vocational colleges and completed the self-administered questionnaire. Diagnostic interviewing was conducted for 333 of the total participants by a psychiatrist with the Chinese version of Schedules of Clinical Assessment in Neuropsychiatry to identify the social phobic cases. Then, the psychometric properties were examined.

於三所五年制专科学校抽取一至三年级学生共369名完成自填「台湾青少年社交畏惧症评量表」，其中333名再经由精神科医师以中文版神经精神医学临床评估表进行会谈，确立是否符合DSM-IV或ICD-10-DCR之社交畏惧症诊断，并依据检测结果进行各种信度与效度评估。

The latest tender has set a minimum price of 10% of the company's nominal value in an attempt to draw out more interest.

最近的招标设定的最低价格为公司票面价值的10%，此次设定的价格是为了抽取更多利润。

METHODS: By cluster sampling, 214 cadets from a military academy were investigated with Modified Big Five Personality Scale and selfdesigned decisionmaking scale. The cadets were randomly divided into 2 groups. After noneffective questionnaires were eliminated, the first group (n=110) were in a positive framing and the second group (n=104) in a negative framing. A chisquare test was used to analyze the results of program chosen and t test was used to determine the relationship between personality dimension and risky choice.

采用自编决策问题问卷和大五人格量表中国修订版，以整群抽样的方法，抽取某军校大学生220人为研究对象，随机分为两组，剔除无效问卷后，正面框架组(n=110)，负面框架组(n=104)，对两组间被试的方案选择进行χ2检验，方案选择与人格特征的关系进行t检验。

Since the size of image covariance matrices is same as that of images and the within-class image covariance matrix is usual nonsingular, thus, the difficulty resulting from high dimensionality and singular case are artfully avoided.

该文提出了一种基于复向量进行特征表不的并行融合新策略，建立了复线性投影分析的理论，给出了复特征空间内进行线性特征抽取方法，事实上，经典的线性投影分析理论与方法只是本文理论与方法的一个特例。

It mainly finished the following several jobs. Pretreated the documents. Improved the Okapi term weighting formula. It also separated the term weighting and completed attributes reduction and rules extraction tasks. Firstly it reduced the feature vector dimensions by using discernible matrix. Then reduced it again by computing relative reductions.

主要完成了以下几个方面的任务：对文本进行了预处理；改进了Okapi权重计算公式，并对权值进行了离散化；实现了属性约简和规则抽取，首先利用区分矩阵对特征向量维数进行了初次压缩，然后通过相对约简计算再次压缩了特征向量维数，并生成了决策规则；采取了规则合成的策略，生成最终的决策规则；设计了一种文本与规则的匹配算法，使匹配过程尽可能简单有序。
