本文对专家系统技术在轮胎花纹设计中的应用理论和实用技术进行了探讨和研究，建立了面向对象的轮胎花纹参数化图元库和花纹设计、选型、载剪、组合专家系统的规则库，并利用面向对象的专家系统骨架研制了轮胎花纹设计专家系统。

On the basis of the analysis of the influence of the object oriented language to software test, this article discusses the tactic and technology for object oriented software test, and proposes an idea and method to test the class as a basic test unit.

本文在分析面向对象程序设计语言对软件测试影响的基础上，讨论了面向对象软件测试的测试策略及测试技术，提出了将对类层的测试作为基本的单元测试的思想和方法。

The "self studying " of the system in operation makes it continuously self-perfecting and more adaptive, then become a users system with the property of community, adaptive and easy use.

该系统基于面向对象特征技术及典型零件加工工艺路线模式化特点提出了一种cAPP系统工艺路线决策方法—面向对象特征的模板式工艺决策方法。

And third, a substantive shift has taken place in the development stance of Tibetan culture, from the self-enclosed, stagnating and shrinking situation to a new stance--the stance of opening-up and development oriented to modernization and the outside world.

三是西藏文化的发展态势发生了实质性的变化，打破了封闭、停滞和萎缩状态，形成了面向现代化、面向世界的开放和发展态势，在传统文化得到弘扬的同时，现代科技教育和新闻传播文化从无到有，获得了空前发展。

的发展态势发生了实质性的变化，打破了封闭、停滞和萎缩状态，形成了面向现代化、面向世界的开放和发展态势，在传统''。

After the analysis of existing safety management system, we design and develop the Rail Traffic Engineering Safety Management System which is based on the Beijing subway line 6 construction .

讨论了工程安全管理系统的特点、建设背景及要点，对生命周期法、原型法、面向对象法三种软件开发方法进行了分析，着重对面向对象开发法进行了介绍。

Socialist China is standing rock-firm in the East, oriented toward modernization, the world and the future.

化、面向世界、面向未来的社会主义中国巍然屹立在世界东方。

Unified Modeling Language has been one of the effective and popular modeling languages for object-oriented software development, so there is a necessity for unification of UML mode and database design which will improve the extendability and robustness of database model.

现在的开发环境多数是面向对象的，而存储机制往往是基于功能分解的关系型数据库，同时在DBMS支持的数据库模型中，关系型数据库是最普遍的，因而就存在将面向对象的思想和关系数据库模型相统一的问题。

Its unique specialized publishing program directed to sophisticated gardeners, horticulturists, botanists, naturalists, landscape professionals -- in short, all people with a keen interest in the world of plants.

它的独特的专业出版计划直接面向富有经验的园艺师、园艺学家、植物学家、自然学者、园林设计专家—总之是面向对植物世界有浓厚兴趣的所有人们。

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。

The split between the two groups can hardly be papered over.
