However, it can only implement the limited operation to the spatial objects, cannot carry on transformation, index, interlink age and excavation to the spatial data, and hard integrate other information with combining map variable to set up and analysis new variable. Meanwhile, relational model in the traditional DBMS and the object- oriented modeling do not completely suit the spatial application domain. The relational model can handle topological relation well, but shows inabilities to that complicated level crossing the spatial region. Object-oriented model using software method based on the principle of the customer defined data type supports the abstract data type, especially spatial abstract data type, and possesses polymorphism and inheritances, and it can deal with topological and the layer relation, but hardly processes important continuous phenomenon in space.

GIS是当今操作有关空间信息的成熟工具和技术，但其只能对空间对象进行有限的操作，不能对空间数据进行变换、索引、链接和挖掘，难以集成其他信息来构建和分析新变量；而传统数据库管理模型中的关系模型和面向对象建模也不完全适合空间应用这一领域，关系模型能够较好地处理拓扑关系，但对表示横跨空间区域的复杂层次却无能为力；面向对象模型的软件方法支持抽象数据类型，特别是空间抽象数据类型，具有继承性和多态性，能够处理拓扑和层次关系，但难以处理空间中重要的连续性现象。

Previously, lithologies and sedimentary environments were commonly identified through core observation and/or comprehensive analysis of sample log data. However, the application of these methods is constrained because the core data and sample log data acquired during drilling are limited. The trend is to identify sedimentary facies through the integration of various log data.

在钻井过程中，取心及岩屑录井资料都十分有限，以往通过岩心观察或者综合分析岩屑录井资料来进行岩性和沉积环境研究的方法受到很大限制，而利用各种测井资料所提供的丰富信息来进行沉积相研究已成为发展趋势。

This encompasses the development of a corporate data dictionary with the organisation ' s data syntax rules, data classification scheme and security levels. This process improves the quality of management decision making by making sure that reliable and secure information is provided, and it enables rationalising information systems resources to appropriately match business strategies. This IT process is also needed to increase accountability for the integrity and security of data and to enhance the effectiveness and control of sharing information across applications and entities.

这包括以业务方的数据语法规则建立合适的数据字典、数据分类方案以及安全等级；在确信已提供了可靠、安全信息的前提下，通过这个过程能提升管理决策水平，并且能将信息系统和业务系统有机地结合在一起；这个 IT 过程还可以增加数据的集成度和安全度方面的考量，以期增强应用和实体间信息共享的效率和控制。

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

As for the mid-June 2006 Mei-yu case, the assimilation of both kinds of data can help the simulation of radar reflectivity. Further investigations show that the assimilation of dropsonde and QuikSCAT data produces stronger southerly environmental winds in the Bilis case, resulting in a better simulated track than the runs without these data. In these runs, the simulated tracks are too far to the south compared with the observed. In the Kaemi case, the tracks of simulations without dropsonde/QuikSCAT data assimilation were shifted to the north/south of the observed track, respectively.

从影响实验研究发现，同化投落送及QuikSCAT资料后，碧利斯台风个案於模拟后期具有较强的南风分量，使其模拟路径不至於像未同化该两种资料者过於偏南；凯米台风个案同化投落送资料后於模拟后期具有较弱的南风分量，而同化QuikSCAT资料后则具有较强的南风分量，使其模拟路径不至於像未同化投落送及QuikSCAT资料者过於偏北及偏南，而与观测路径较为接近。

In this paper the Kelantan in Malaysia is used as the study area. On the base of the regional flood disaster theory and fuzzy synthetic evaluation method, integrating remote sensing data, ground meteorological data, rainfall data, social and economic data, using the technology of geography information system, flood disaster risk assessment models are built.

本文以马来西亚吉兰丹州为研究区，以区域洪水灾害系统理论及模糊综合评价方法为理论基础，基于遥感数据、地理背景数据、降雨数据及社会经济数据，运用地理信息系统建模技术，构建了洪水灾害风险评估模型库。

A128 有3参量。参量1：当前的数据集状态(新建，共享，已存在并当前独占，新建并独占)；参量2：数据集正常结束；参量3：数据集异常结束。

At the same time, those design indexes is realized well by means of selecting superior performance electronic apparatus abortively. Because of a great deal of digital EEG data and the demands on real-time display and synchronous data acquisition, a kind of multi-channel synchronous data acquisition system is

由于数字化的脑电信号数据量大，为满足实时显示以及同步采集脑电信号的要求，设计出了基于双端口和USB通讯接口的多通道同步数据采集系统，使脑电图仪与微机之间进行高速、可靠的数据传输成为可能。

With this method instead of importing data from one server to the other, you can let the data reside where it is but instead use the linked server capability to access the data.

用此方法而不是输入数据从一台服务器的其他，您可以让数据在那里居住的是，而是使用链接服务器能力来存取数据。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.
