The algorithms of MUSIC and ESPRIT are introduced, which are the most important algorithms in array signal processing. A method is proposed to make the estimation of the covariance matrix become Toeplitz matrix using the Toeplitz characteristic of covariance matrix.

第2章建立了阵列信号的模型，主要分析了两种无方向模糊的阵列：阵元数大于6的均匀圆阵和非均匀L形线性阵列，并讨论了非均匀L形线性阵列无模糊设计的方法；然后介绍了在阵列信号处理中，两种最主要的算法：MUSIC算法和ESPRIT算法。

Based on the molecular topological theory, a modified group dyeing indexL is introduced. It is used in the study of refractive index of the ketones and ethers. Relationship between the refractive index and molecular structure of 57 ketones and ethers is studied by using quantitative structure-property relationship technique. The reasonable molecular modeling equations are obtained by multiple regression for the prediction of the refractive index of ketones and ethers.

在分子拓扑理论的基础上，提出了一个修正的基团染色指数L，运用定量结构－性质相关技术研究了57种酮类和醚类化合物分子的折射率与分子结构间的定量关系；通过多元回归的方法建立了L与折射率的定量结构－性质相关模型。

One-component epoxy structural adhesive is made up of epoxy resin,L curing agent,100 b which is promotion at a certain proportion,with toughener such as liquid nitrile,QS-BC,QS-BE,EPG,QS-210B.

将环氧树脂、L固化剂、促进剂100b等按一定比例配成单组分环氧结构胶粘剂，辅以液体丁腈橡胶、QS-BC、QS-BE、EPG、QS-210B等增韧剂。

This paper briefs the basic principles of " transitive closure " cluster analysis based on fuzzy equivalent relation and fuzzy ISODATA cluster analysis based on soft division technique, and advances a classification and recognition method by combining K-L transformation and the two fuzzy cluster methods above, which makes full use of the advantages of both cluster methods.

介绍了基于模糊等价关系的"传递包"聚类和基于软划分的模糊ISODATA聚类2种模糊聚类分析方法的基本原理，充分利用2种方法的优点，提出了一种将K-L变换与上述2种模糊聚类方法相结合的分类识别方法。

The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。
