The comonomer in the copolymer by cat247 is trend to isolated. A few amount of comonomer could make the melting point remarkably decreased and maintain the crystalline at a relative high level. This catalyst can be use to produce the material with low melting point and high intensity such as packing film with low hotsealing temperature. The copolymer by cat24 is characteristic of uniform comonomer distribution and low melting temperature and crystallinity. Therefore, this catalyst could be used to produce LLDPE and POE according the comonomer content; cat246 has a strong copolymerization ability, and the resultant polymer has relatively high blockiness. If this trend is strengthened by adjustment of polymerization condition, the polymer can be used as thermal plastic elastomer with random and crystalline blocks.

由于各个催化剂所产生的聚合物各具特点，所以其潜在的工业用途不同。cat247的产物中共单体趋于孤立分布，极少的共单体即可使熔点明显降低而结晶度仍保持较高水平，有利于制备低熔点、高强度的材料（如低热封温度的包装膜等）。cat24的催化聚合产物无规程度比较高，对降低熔点和结晶度都十分有效，通过控制产物中共单体含量的多少，可以生产LLDPE和POE；cat246共聚合能力强，且产物有嵌段倾向，通过调整聚合条件强化这一倾向后，可以用来生产具有无规-结晶嵌段结构的热塑性弹性体。

I used to watch James Brown on the television,and I used to get angry at the cameramen because when ever he could really start to dance,they would be on a close-up so I couldn't see his feet.

我以前经常在电视上看詹姆斯布朗表演，每次他真正开始舞蹈的时候我就非常生摄影师的气，他们总是给他一个大特写镜头，我就看不见他的脚，于是我就大叫，"拍他的脚，拍他的脚"这样我就可以学

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 results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.
