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。

The accounting information is the concentrated reflection of listed companies. Its quality directly influences the effective degree of capital market, the disposition efficiency of social resources as well as the accounting information in the supply-demand balance process. At the same time, the full disclosure of accounting information may save the transaction cost because of reducing the degree of information asymmetry in the release and the transaction process in the stock market.

会计信息，是上市公司经营状况的集中反映，其质量的高低直接决定着资本市场的有效程度、社会资源的配置效率以及会计信息在供求方面平衡过程；同时，会计信息的充分披露，可因降低证券市场发行与交易过程中的信息不对称而节约交易成本。

In accordance with the notification, development and reform departments, economic and trade departments must take immediate action to publish and update the regional energy-saving reduction in fixed asset investment information, corporate energy-saving information, timely notification to the financial sector, industrial restructuring, circular economy, energy transformation, energy-saving technologies and products such as directory-oriented industrial policy, project evaluation of the review of energy-saving, business energy audits, cleaner production audit, the law of energy and other enterprises to use energy-saving information, as well as advanced energy-saving incentives for emission reduction, financial information such as financial support for the project.

根据通知，发展改革部门、经贸部门要及时公布和更新区域节能减排固定资产投资信息、企业节能信息，及时向金融部门通报产业结构调整、循环经济、节能改造、节能技术和产品等产业政策导向目录，项目节能评估审查、企业能源审计、清洁生产审核、违法用能等企业节能用能信息以及节能减排先进奖励、财政资金支持项目等信息。

With the development of the technology of information and computer, the information resource become more and more transparent, so people play more and more attention to the security of information, so the random number plays an important role in the security of information.

随着信息技术和计算机技术的飞速发展，信息资源公开化程度越来越高，这使得信息安全越来越受到人们的关注，而随机数在信息安全中有着重要的地位。

Limitations of Shannon's information theory and information definition are analyzed from new angles. It is pointed out that they didn't consider the reliability, completeness and other characteristics of information, and the naming of conditional entropy is not proper. The correct naming of Shannon's "conditional entropy" should be weighted average conditional entropy. Examples are given to illustrate the conditional entropy maybe increased, so Shannon's definition of information is not absolutely correct.

从新的角度指出了香农信息论和信息定义的局限性，指出了它没有考虑信息的可靠性，完备性等特点，指出条件熵的命名不恰当，香农的"条件熵"应该称为加权平均条件熵，并且举例证明了条件熵可能增加，进而香农信息定义中的不确定性的减少也不是绝对的。
