The research includes the transform of time series , the measure of the similarity , the index for the time series database , and the process of the similarity query . the work and contributions are listed as following : 1 we present a time series segmenting method to present the changing pattern of time series 本文研究了基于序列变化模式的相似性查询方法，包括序列变化模式的表示、全序列查询、子序列查询、序列数据的聚类以及基于簇的序列查询，提出了完整的基于序列变换模式的相似性查询方法，主要的研究内容和研究成果如下： 1
On the base of query demand for semantics , this thesis synthetically analyzes the performances and backdrops of xml 、 rdf and owl ontology query languages presently , brings forward a query means , it combines both template and query language mechanisms , surmounts localizations of single query language , enhances capacity of query and it is easy to realize query to heterogeneous data sources 本文针对本体查询语言基于语义的查询需求,通过对目前主流的xml 、 rdf和owl查询语言性能和使用情况的综合分析,提出了一种本体查询方法,该方法把查询语言与查询模板两种查询机制结合起来,克服了单一查询语言的片面性,提高了查询的智能,可以方便的实现对异质数据源的查询。
With the rapid development of databases techniques and computer network , large amount of data is stored , the rapid growth demand for extracting , understanding and assimilating useful knowledge from the growing mountains of data outspaces the traditional methods of data analysis , which leads to the emerging field of knowledge discovery in databases and data mining . rough set theory is new maths tools , and its characteristic have no need of other existing information , which make it overcome shortcoming of other methods and avoid the influence of subjective factor to the results of datamining . and become one of primary methods of kdd 传统的数据分析和查询方法已不能满足人们对隐藏在数据背后的知识的迫切需要，在这种社会需求的强劲推动下，知识发现和数据挖掘应运而生，而粗集理论作为一门新的数学工具，凭借它不需要附加任何外界信息或先验知识这一特点，突破了其它数据分析工具的局限，避免了人的主观因素对数据挖掘结果的影响，逐渐成为了研究知识发现的重要的数学工具之一。
With regard to rough data query , the focus is firstly placed on analysis of advantages and disadvantages different methods bear in dealing with this problem , and a new method of rough query based on sql is put forward in this chapter . this method can improve efficiency of query , decrease storage space and posses a good application values 在粗糙数据查询方面，分析了各种粗糙查询方法的优缺点，提出了一种基于sql语言的粗糙数据查询方法，该方法可以提高查询效率，减少存储空间，具有较好的应用价值。
Analysis on anomaly alerts provides an opportunity to learn the new attack , but the related detail information about that attack is lacked . in our algorithm , a method combining trap - node attack information gathering with anomaly alerts query is presented to create a new way to learn novel attack mode 根据信息融合摘要西北工业人学博卜学位论文提出了异常分析目标，利用陷阱主机的信息采样方式，结合异常查询方法，在攻击信息融合中成功地提出了攻击异常分析的解决途径。
According to the prospecting correlation standard classification method , based on the combination of windows nt server , iis5 . x , asp . net and oracle 9i , the article introduces how to design the correlation standard information classification search system for daqing oilfield prospecting with three - layer system structure of the b / s mode using visual c # . net , dreamweaver and other softwares . using the accurate or fuzzy search method , table looking up and other search method , the search system studied in this article can be used to search standard numbers , standard names and stamdard system structure of the prospecting correlation standards . with com add - in built using visual c # . net , it realizes office browsing through web pages 以windowsntserver + iis5 . x + asp . net + oracle9i的组合为技术支撑,根据勘探相关标准分类方法,结合visualc # . net 、 dreamweaver等软件,采用b / s模式三层体系结构,设计了大庆油田勘探相关标准信息分类查询系统;利用精确或模糊及体系表等查询方法实现了勘探相关标准的标准号、标准名称查询及体系标准结构查询,利用visualc # . net建立comadd - in ,实现web上的office浏览。
I also made a simple discussion on how to use www and asp to do distant education and supporting on marine machinery maintenance , and a sample system was provided . in this system , the marine mechanical devices are sorted by level and coded respectively ; a distant query method based on asp and ado is designed by which the user can access the system from client - side browser ; common mechanical defaults , detecting methods , default - avoiding methods and repairing methods are demonstrated in the form of web page ; a specialized bbs on marine machinery maintenance is also provided as a communication tool 本系统的开发利用asp技术初步建立了船机维修远程教育及支持系统，对于船机设备、零部件作了层次性的划分，提出了相应的编码方法；对于船机设备、零部件常见的失效形式、检测方法、预防措施、修复工艺进行了搜集与整理并进行了编码；设计了分级的远程查询方法；以页面的形式展示了各种失效形式、检测方法、预防措施和修复工艺；提供了船机维修网上专业论坛；初步实现了系统开发的目标。
