Concept data model of MRGISDM analyses entity's character and relationship. Logic data model designs logical and geometric representation of entity and relathionship; physical data model designs the schema of classification and coding ,orgnization of layers,and physical storage structure.

在MRGISDM概念模型中确定了市政道路中需要表达的要素实体，提取出每个要素实体的属性，并描述出实体之间的关系；MRGISDM逻辑模型则把市政道路实体以及实体之间的关系表达成地理信息系统所能识别的方式，并用UML语言等工具描述成UML逻辑模型图；MRGISDM物理模型从市政道路要素的分类与编码、图层的组织以及物理表结构等几个方面来设计市政道路要素的组织和存储结构。

With the development of the computer technology and network technology, various kinds of data present the exploding type of geometric series to increase. Various kinds of online data increase rapidly. This impels the storage capacity of the data to increase sharply at the speed of 3 to 5 times of every year.

随着计算机技术和网络技术的飞速发展，由此产生的各种数据呈几何级数爆炸式增长，各种在线数据增长迅速，促使数据存储容量以每年3 到5 倍的速度急剧增加。

Along with time fast vicissitude, the former information is not easy the seal society which circulates, gradually transforms the open society which the information explodes. All information could get by information science and technology. For example, the television, broadcast or Internet and so on.But so huge information quantity has surpassed the limit which the people brains can process.Therefore, how to avoid "GIGO", needs to depend on the information science and technology to solve. Data Mining is a very good method. The goal is extracts particular and useful information or knowledge of users from huge data. And data mining may divide into very variously, this paper is does take "Sequential Pattern" as the research subject.

随著时代的快速变迁，以往资讯不易流通的封闭性社会，逐渐转变成资讯爆炸的开放性社会，所有的资讯，皆可由电视、广播或是网际网路等资讯科技来获得，但如此庞大的资讯数量，已超出了人们头脑所能处理的极限，所以如何避免「GIGO」，需要靠资讯科技的技术来解决，「资料探勘」即是其中一个，目的就是要从巨量的资料量中，粹取出使用者所特定、渴望的资讯或知识，而资料探勘可分为很多方面，本篇论文是以「序列型样」来做为研究的主题。

Diana Glassman, a data protection expert, says that a useful first step would be for the boss to write to all employees reminding them of the risks and potential cost of data leakage, and asking them, before passing data to anyone else, to question whether that person truly needs, or is entitled to, it.

格莱斯曼说，对老板来说有效的第一步应是写信给所有员工，提醒他们数据泄漏将开来风险和潜在成本，同时让他们，在将数据传送到其他任何人之前，想一想是否那个人真的需要这些数据或者有权拥有数据。

Graphical method based on CAD is used for measurement data processing, instead of manual calculation. Graphical method based on CAD may improve the efficiency of data processing and data precision.

采用CAD图解技术是完全能够替代以往以人工计算为主的测量数据处理的方法，并能大幅提高数据处理效率，提高数据的精度。

The vertical diffusivity coefficient of the South China Sea is studied by the adjoint data assimilation method in this thesis. The satellite data SST and the harmonic constant of M2, S2, Kb 0, extracted from TOPEX/POSEIDON satellite altimeter are used in data assimilation. So the average of the vertical diffusivity coefficients of the South China Sea in the thermocline in January, April, July, October, 1997 are2.2 10-4/m2s-1, 7.8 10-5m2s-1 , 1.0 10-4m2s-1 , 1.0 10-4m2s-1 respectively.
