In this dissertation, based on the extraction of meaningful polarization information, the polarimetric speckle reduction, polarimetric contrast enhancement, polarimetric classification and ship detection in polarimetric SAR images are systemically studied. During the study, some new concepts and methods are introduced, which are supported by the application to measured Pol-SAR data. The innovations of this dissertation are as follows: 1 A simplified schem is proposed to reduce the complexity of scattering-model-based speckle filtering. 2 Extend the expression of polarimetric correlation coefficient to help distinguishing targets. In addition, introduce the quantized parameters of polarimetric signature so as to show the differentiae in quantity in co-polar power, cross-polar power and shapes of polarization signatures among targets. 3 Define a new parameter of difference degree between targets, which can be used for express the difference between both coherent and distributed scatters.

论文在较系统的研究目标特征量提取方法和特征量所包含的物理意义的基础上，对极化SAR图像降斑、极化对比增强、极化SAR图像分类以及极化SAR图像中海上舰船目标检测等方面进行了研究，并提出了一些新的概念和方法，对实测数据的处理结果表明，这些新的概念和方法对于极化SAR信息处理是有效的，本文的主要创新成果包括以下方面： 1）针对基于预分类的MMSE极化降斑方法实现过程非常复杂的问题，提出了简化方案，并验证了方案的有效性； 2）扩展了极化相关系数的表示方法，这种扩展增强了极化相关系数对目标的区分效果；另外还提出了极化特征图量化参数，可以从量上表征不同目标间相同极化和交叉极化的回波功率差异和极化特征图形状差异； 3）定义了目标间的差异度参数，它不仅可以用于描述相干目标，还可以用于描述分布目标的差别程度。

The second part of the article studied the classification of Electroacoustic music from the perspective of its historical and technological development, from the "Electronic piecing music","Synthesizer music" to the "Computer digital music" today. The method of classification was based on the consideration of the creation of Electroacoustic music.

第二部分从历史和技术的角度对电子音乐做了分类的研究，从早期的电子拼接音乐到电子音合成音乐再到当今的电子计算机音乐，这种分类的方式主要是从电子音乐的创作方式来考虑的。

Aimed at the study of Lauraceae system classification in domestic and overseas,genetic diversity and genetic variation between Cinnamomun micranthum Hayata natural populations and Ex-situ conservation poputations and relationship among Its Close Relative Species of Cinnamomum camphora Presl,Cinnamomum burmannii(C.G.etTh.Nee) Bl,Phoebe bournei Yang. Litsea subcoriacea Yang et P.H.Huan. Neolitsea aurata Koidz,Lindera communis Hemsl and Persea Americana Mill.were studied by inter-simple sequence repeats molecular marker.The research aimed at genetic variation between Cinnamomun micranthum Hayata populations,so that can offer the molecular theoretic and practical method for conservation and utilization of Cinnamomun micranthum Hayata populations.

针对目前国内外对樟科植物系统分类的研究现状，本研究采用ISSR分子标记技术对樟科沉水樟天然居群和迁地保护居群的遗传多样性进行研究，从分子水平上分析沉水樟种群的生态遗传及其遗传变异规律；同时利用ISSR分子标记技术比较沉水樟及其近缘种香樟、阴香、闽楠、桂北木姜子、新木姜子、香叶树、鳄梨在分子水平上的亲缘关系，揭示这些树种在樟科植物系统进化中的作用与地位，探讨沉水樟及其近缘种的遗传多样性及其分化格局，为樟科植物的系统分类提供分子水平的依据。

Department of computer, jiangxi institute of commerce, nanchang 330100, chinaabstract: clustering is a process that assorts things by their similarity,traditional clustering analysis assorts things strictly, therefore the border of the classification is very clearly.

聚类就是按照事物间的相似性进行区分和分类的过程，传统的聚类分析是一种硬划分，它把每个待辨识的对象严格地划分到某个类中，具有非此即彼的性质，因此这种分类的类别界限是分明的。

By the analysis of the misty classification to the plant diversity of Nanyue nature reserve area and its 9 vicinities,The results show that:By their relationship of Nanyue nature reserve area and its 9 vicinities,the result is: Taiwan Area＞Jinggang Mountain＞Wuyishan Scenery＞Daluo Mountain＞Baiyun Mountain＞BaiShan Mountain＞BaiChuang Mountain＞Huangshan Mountain＞Xinnongjia.In order to do a beneficial tries and investigate a new plant classification method,and meanwhile the results is very meaningful to the management and reservation of Nanyue nature reserve area.

本文通过对南岳自然保护区植物多样性与其相邻的其余的9个地区植物多样性进行模糊聚类分析，结果表明，按与其区系关系的密切程度的大小进行排列，与南岳自然保护区的关系的密切从大至小的顺序为：台湾岛＞井冈山＞武夷山＞大罗山＞白云山＞北山＞北仑山＞黄山＞神农架，旨在对植物区系分类方法的研究作一个有益的尝试，探索一条植物区系分类的新方法，同时其结果对南岳自然保护区的经营管理和保护具有一定的实践指导意义。

Firstly, we summed up the process and results of historical research. And then we classified the action morpheme and the noun morpheme. Based on the classification, we analyzed noun morphemes in order to find which kind of noun morpheme is strong to unite and which is the weak ones to centre around the action morpheme. Then we stated, analyzed and accounted for the usage of different semantic categories used in the line situation. We found that action morpheme combined into one by moving the line word was the main line and the main format, and explored and analyzed the role of analogy of noun morpheme line to other formats. Line formation of the word has its own reasons, so the article concluded by examining the formation of the line words' language, social and other reasons at last.

文章着眼于对动、名语素组合成的离合词的语义构成进行分析，探讨了动、名语素组合成离合词的语义选择规律，以动、名语素的语义分类为基点，在分类的基础上，以动语素为中心，分析围绕动语素的名语素义类，分析哪些义类名语素和动语素组合成离合词的能产性较强，即组合的周遍性和数量频度上是最高的，哪些义类组合成离合词的能产性比较弱，试图寻找动语素与名语素组合成离合词在义类上的能产性和周遍性，然后再对不同语义类组合中离合运用的情况进行统计、分析、说明。
