Because the information in groupware system has Characteristic of complex, various, large quantity, non-structure or structure complex, close relativity of information, etc, and the traditional relational database can hardly handle these complex and various information. This paper aims at the problems that groupware system meets in application, put forward the research on groupware system based on object-oriented database management system.

由于群件系统中所处理的信息具有复杂、多样、量大、非结构化或结构复杂以及信息间的相关性紧密等特征，而传统的关系型数据库很难处理这些复杂多样的信息，因此，本文针对群件系统对数据库的应用需求，提出了基于面向对象数据库管理系统的群件系统的研究。

In this paper, based on the idea of knowledge constructionism, a structural knowledge representation approach is proposed. The "Unit" is defined as the essential knowledge component, and ten types of units and relations between units are suggested.

本文以认知科学中的知识建构理论为基础提出了一种结构化知识表示方法，此方法以"单元"作为知识表示的基本结构模块，将单元划分为十种类型，并定义了单元之间的关系。

By applying Simon's idea of system's near decomposability, the quantitative structuralization method is proposed based on the QMT3 (quantification method of type 3). Furthermore, the features of this method are clarified by comparison with the current methods. Finally, the effectiveness of the method for software structure analysis and design is verified by an application.

西蒙的系统准分解可能性原理，提出了基于数量化理论3类QMT3(quantification method of type 3)的软件定量结构化方法，再通过与现有方法的比较分析，阐明了该方法的特点；最后，通过应用实例验证了该方法对软件结构分析和设计的有效性。

Based on goal-scenario coupling and conception attribute, this paper presents a structured method of goal description and identification,constructs goal model, describes and identifies goals. Integrated with the goal-driven software architecture modeling method smoothly, the methodimproves the development quality and production efficiency of information system.

摘 要：基于Goal-scenario coupling 理念，提出了一种基于概念属性的结构化目标描述与识别方法，构造了目标模型，对目标进行了描述和识别，该方法可以与目标驱动的软件体系结构建模方法进行平滑集成，提高了信息系统的开发质量和生产效率。

The main omissions are extended-precision arithmetic; the goto statement; nonstructured forms of switch such as Duff's device; passing struct and union parameters and results by value; and functions with variable numbers of arguments.

而忽略的主要是扩展精度类型的算术运算(long long和long double)； goto 语句；如达夫设备(Duff's device)之类的非结构化switch转移；结构体、联合体参数传递和结果值返回；以及带有变长参数的函数。

Besides being well designed, Python is also well tooled for modern software methodologies such as structured, modular, and object-oriented design, which allow code to be written once and reused many times.

除了是精心设计的，Python也使用了现代软件方法，如结构化，模块化，面向对象设计，使代码写一次，可重复使用多次。

Furthermore,the software,which has been designed with the object-oriented technology and the visualization technology,constructs a platform for professionals to design power supply system in urban rail transportation.

该软件采用成熟的关系型数据库SQLServer 2 0 0 0 ，以BorlandC ++Builder作为开发工具，结合可视化与结构化技术，构建了一个城市轨道交通供电系统设计的平台

This research job analysised the extending roll pass system the finish roll pass system and the ultimate roll groove. The mathematical models and experience formulations used for roll pass design are corrected according to the basic theory and the practical experience of the engineerings. The thread steel bar CARD was set up with the visual program tool-VisualBasic6.0, based on the method of the structural program design.

本课题通过对螺纹钢延伸孔型系统、精轧孔型系统及成品孔型的构成和设计方法的分析，结合螺纹钢孔型系统的基本设计理论和工程技术人员的实际生产经验，对以往孔型设计过程中所使用的数学模型、经验公式等进行了修正，以结构化程序设计方法为基础，采用可视化编程工具VisualBasic6.0建立了螺纹钢计算机辅助孔型设计系统。

Secondly, there is great deal of unstructured documents of agricultural resources.

其次，农业领域中所存在的大量非结构化知识资源的现状，无法直接实现语义化。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
