Gu Ge comes to all these information from the collect on whole Internet, it has all news classified, extraction gives crucial information, these information are no longer provide an user desultorily, help an user search them however most wanted information.

这一切信息都是谷歌从整个互联网上搜集来的，它把所有的信息进行分类，提取出关键信息，这些信息不再是杂乱无章地提供给用户，而是帮助用户寻找他们最想要的信息。

Portal website can provide the news source with powerful user, but the own alternative in reality of the user is weak force, the effectiveness of derive information is more fragile, cast the empty shell of information of numerous and jumbled, find truly hoggish information fact to searched engine to give an user certain autonomy for; of look for a needle in the ocean, the user can have the search of the keyword directly according to oneself demand, get relevant news source then, but the search platform that certain to searching the accuracy of information to still exist insufficient; classifies information to offer user essence to allow, use door can faster more the finds oneself to need information with accurate essence.

门户网站可以提供给用户强大的信息源，但用户的自主选择性实则是弱势的，汲取信息的有效性更是薄弱的，抛开庞杂信息的空壳，找到真正利己的信息实为大海捞针；搜索引擎给予了用户一定的自主性，用户可以根据自身需求直接进行要害词的搜索，进而得到相关的信息源，但是对于搜索信息的准确性还存在一定的不足；分类信息提供给用户精准的搜索平台，使用户能够更快更精准的找到自己需要的信息。

Secondly, two methods are combined into a 2D classifying method and again the current highway information foundation data elements are classified in 2 Dimensions. The problems in data element set are pointed out and also the expand idea is put forward. The key properties of 2D classifying data element are studied.

将2种分类方法结合形成二维数据元分类方法，并对现有公路信息基础数据元重新进行了分类，指出存在问题并给出了数据元扩充的思路，对二维数据元的关键属性进行了研究。

Has formed the main function in view of these question this financial control system designs: Has solved the traditional manual with difficulty long-term preservation problem; Has the certainly fast inquiry function; In the number financial control also has even if the renewal system information function has the classified statistics function; When carries on the classification statistical work is arduous, in prompt discovery and solution management question; Enhanced between other department's data inquiry working efficiency favor the establishment company interior the information exchange platform, was advantageous for realization company interior resources sharing.

针对这些问题本财务管理系统设计而形成了主要功能：解决了传统手工难以长期保存的问题；拥有一定快速的查询功能；在数财务管理还拥有即使更新系统信息的功能具有分类统计功能；在进行分类统计工作繁重时，及时发现和解决管理中的问题；提高了其它部门之间的数据查询工作效率利于建立公司内部的信息交流平台，便于实现公司内部的资源共享。

The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study

城乡交错带地区的景观分类，在对城市地区和农村地区的土地利用类型研究的基础上建立了城乡交错带的分类体系，并在此基础上用ARC＼INFO软件分时段、分区、分要素建立研究区的景观图形数据库，对数据进行存储、修改和管理；2）利用多种景观结构、格局指数和斑块面积谱分析方法，从不同的侧面对各种景观组分的结构以及区域的景观格局特征进行了分析，并对其成因进行了探讨；3）利用相同的分析方法，分析了城乡交错带中的城市干道两侧的景观格局特征的空间和时间分异情况，初步掌握上海城市西南轴向扩张的基本过程和规律；4）对城乡交错带中非独立的景观要素-植被，研究其遥感图象信息的基本特征，建立适合区域特点的植被分类体系，并在样区中建立了植被图形数据库和计算机制图，分析了植被景观种类组成、斑块等级等特征以及与不同景观的相互关系；5）在上述研究的基础上，对研究区内的景观生态对策进行了研究。

An inductive learning method for classification based on information theory is proposed, which is a maximum contribution classification method according to the theory of channel transmission in information theory, the definition contribution is developed based on probability distribution of classified space, probability transfer matrices of classified space and feature space and mutual information, then entities is classified by the maximum contribution method.

提出了一种基于信息论的归纳分类学习算法－最大贡献分类算法。该算法根据信息论中信道传输的理论，把类别空间和各特征空间的概率转移矩阵以及互信息结合起来，定义了贡献的概念，从而得出了对给定的观测值，用它的最大贡献作为对实体进行分类的规则。

The dissertation is focus on establishing a user model for personalized information retrieval based on user partialness keyword list, including classified dictionary, study module, user behavior monitor module, Internet change detecting module, document analysis and information filtering module, and with the communications and collaboration of these modules, the model obtains on load of user partialness information while in inquiring, retrieving and results filtering. Thus the precision of information retrieval increases, and it can keep up with the change of webpage, and personalized information retrieval service realized.

本文的主要工作是在客户端建立基于用户偏好关键词表的用户个性化信息检索模型，包括分类词典、学习模块、用户行为监测模块、Internet变化检测模块及文档分析与信息过滤模块，并通过各模块之间的通信协作来实现用户查询提问时、信息检索过程中和检索结果过滤时用户偏好信息的加载，来提高检索结果的精度和跟踪网页信息的变化，从而实现个性化信息服务。

The new method for seismic attribute analysis colligates information of seismic,logs and geology by crossplot and broadcast and cluster with the methodology of science instead of analysis with handcraft and eyeballing.With the method,seismic attribute analysis plays an important role in subtle traps exploration. \r\n

指出新型的地震属性分析方法一改以往的手工、目测分析方法，充分利用了二维、三维及多维交汇方法，为属性分选、分析提供了便利的操作手段；新型的地震属性方法还运用科学分类方法，综合地震、测井、地质信息，把剖面、平面及分类结果结合到一起，通过三维一体的相互信息映射，在储层预测中的目标初选及目标分析中起到了举足轻重的作用，真正做到了属性分析的科学性、实用性。

Last year, the port city enterprise implemented "walks" the strategy to make the new progress, the foreign economic cooperation service has had the large growth, the big project impetus service grew, beyond the border foreign contract engineering service, mainly occupied "the big end" by the architecture industry, realized grew quickly, compared with last year, the rate of rise was remarkable, sends out the population also largely to increase, launches the foreign economic cooperation project, adapted the international contract market development.
