变量

Abstract〕similar to regression analysis,cluster analysis,etc.,correlation analysis is also the basic work for information researches.canonical correlation analysis can be used to analyze the relationship between two groups of variables,and thus worth for using in information science.method of canonical correlation analysis was presented in present study.a java-based network algorithm of canonical correlation analysis was developed,which can be used to calculate the canonical correlation coefficients,canonical variable pairs,and statistical significance of canonical correlation coefficients.the algorithm may be run on java-compatible web browser.at the same time,paper publishing information and citation statistics in information science of china in past years were analyzed using the algorithm,and a number of conclusions were drawn.

摘 要〕与因果分析等一样，相关分析也是信息资料分析的基本工作。典范相关分析用于分析两组变量之间的关系，在情报信息的相关性分析方面有潜在的应用价值。本研究介绍了典范相关分析方法，给出了典范相关分析的java网络算法软件，可用于计算典范相关系数，典范变量对，以及典范相关系数的统计显著性。该软件可在兼容java的网络浏览器上运行。同时，用该算法对国内情报信息论文的发文和引文统计数据进行了分析，得到了一些结论。

CCA indicates that there are strong integrated correlation between mainstream smoke and the physical and chemical properties, where canonical variable U representing information of mainstream smoke is mainly contributed by TPM, tar, nicotine, vapor, vapor content and puff times; canonical variable V representing physical and chemical information of cigarettes is mainly contributed by ventilation rate, close resistance, cigarettes weight and total sugar, total organic chlorine etc, where ventilation rate plays an important role.

典型相关分析表明：卷烟主流烟气与物理化学信息间存在显著的整体相关，其中反映主流烟气信息的U典型变量主要来自总粒相物、焦油、烟碱、水分、水分含率及抽吸口数的贡献；反映物理、化学指标信息的V典型变量主要来自稀释率、闭式吸阻、单支重及总糖、氯等化学指标的贡献，其中稀释率的作用最大。

The standard canonical variable V1 was mainly affected by SBP and W1 by UA and BUN at almost same degree (V1 = 0.6392*SBP'+ 0.4649*DBP', W1 = 0.6990*UA'+ 0.6430*BUN'), which indicated the higher of UA and BUN the higher of SBP, and the degree of correlation between the SBP with UA and BUN was almost sameness.

其标准典型变量V1 主要受SBP的影响( V1 = 0.6392*SBP'+ 0.4649*DBP')，标准典型变量W1 受UA和BUN的影响程度相当( W1 = 0.6990*UA'+ 0.6430*BUN')，因而可以认为UA、BUN越高的个体其SBP越高，且UA、BUN与SBP的升高的关系基本相同。

Those variables for which it holds (e.g., momentum and position, or energy and time) are canonically conjugate variables in classical physics.

那些具有的变量(如动量与位置，或能量与时间)是经典力学里的正则共轭变量。

Unlike most of Asterisk, variable names are case sensitive.

And found that there is not direct causal relation between the criterion and chattering variables.

发现其判定摆动变量的判据与变量的摆动没有直接的因果关系。

For example,Yuanguo Zhu and Baoding Liu had proposed the concepts of random fuzzy variable s chance distribution,critical values, expected value,moments,and so on.

以随机模糊变量的机会分布为基础，我们已经探讨了很多随机模糊变量的数学性质。
