抽取的

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。

The survey conducted in Taiwan was designed using a multiple-stage sampling method that utilized the principles of probabilities proportional to size, stratified sampling, and systematic sampling to strengthen the sample's effective representation.

为符合研究的需要，本次研究的抽样方法采取较复杂的多阶段抽样法，主要应用「抽取率与单位大小成比例」原则，结合分层抽样、等距抽样等抽样方法的优点，以求提高样本代表性。

The construction of numeral abbreviation can be roughly grouped into four types: subordination, coordination, subject+predicate and verb+object. Among them, subordination occupies the main part. Numeral abbreviation can be derived from either extracting the first, the middle or the last morpheme from its original words or generalizing them. Numeral abbreviation consists of four classes: word, phrase, sentence and text in terms of its original words. Most numeral abbreviations are disyllabic and quadrisyllable, and only a small number of them are trisyllabic and polysyllabic.

数字缩略语的结构有类化的特点，包括偏正式、并列式、主谓式、动宾式等，其中以偏正式为主；在抽取方式上，数字缩略语有抽头式、取中式、取尾式和统括式；从缩略的对象上看，数字缩略语的缩略可分为词、短语、句子和篇章四个层次；在音节分布上，数字缩略语以二、四音节为主，三音节和多音节为辅。

Methods:Stratified quota sampling was used to select four communities,representing different community health service models.

采用分层定额抽样方法，抽取 4个不同类型的社区，以入户调查和面对面访谈的方式共调查居民 4 17名，比较贫困居民和普通居民在卫生服务需求和利用方面的差异，并了解他们对家庭病床的认识。

The establishing process of knowledge base is the learning knowledge process in ANN, so the knowledge base can constantly rechange and enrich.

基于ANN的CAPP系统开发工具的知识库由知识抽取机和学习机共同作用生成，知识库的建立是在网络学习过程的基础上进行的，因而知识库可以不断创新、不断丰富。

If want the data of built-in in HTML page of the static state trends, and these dynamic data are the word that will offer by the program such as ASP, PHP, so every time a person visits your website, the server is about to carry out and handle Tongji.asp document, from the data with draw-out and relevant database, reexport shows to the webpage, if tens of thousands of person is visited at the same time, be about to be carried out tens of thousands of times, consequence cans be imagined.

假如要在静态的HTML页面里嵌入动态的数据，而这些动态的数据是由ASP、PHP等程序来提供的话，这样每次有一个人访问你的网站，服务器就要执行并处理一次tongji.asp文件，从数据库抽取相应的数据，再输出给网页显示，假如有几万个人同时访问，就要执行几万次，后果就可想而知。
