At last , this paper selected the research field of flood dispatcher ' s system of the reservoir , after analysing and studying the characteristics of this application , we researched the application of cbd into the field , and put forward the application framework and the component model of rfds 最后，本文选取了水库洪水调度系统这一研究领域，在分析和研究了该应用领域的特点后，就基于构件的软件开发方法在领域内的应用作了探讨，提出了rfds的应用框架及构件模型。
This text is on the basis of studying some latest conclusions and cases on component technique in academia or industry . in this paper , we make detailed discussion on component technique and component - based software development ( cbd ) , research component concept of flexible equipment , analyse and study the problems and solutions appearing in the course of cbd . in the end , a question model appears 本文在研究国内外构件技术一些最新学术和应用成果的基础上，就构件及基于构件的软件开发( cbd )作了详细的讨论，探讨了构件柔性组装的概念，对基于构件的软件开发过程中出现的问题及其解决方案进行了分析和研究，并给出了一个问题模型。
Accordingly , the status and importance of application server has been recognized promptly . it was claimed that application server was a milestone of the third class system software . especially , component deployment plays a important role in the development , run and test of software component 相应地，为服务器端构件提供运行时环境的应用服务器的地位和重要性也已经被迅速认可，并被认为是继操作系统和数据库系统之后的第三类里程碑式的系统软件，是实现基于构件的软件复用的关键。
Software reuse is one of the important fields of computer research . , integrating with software reuse , distribute computing , case and enterprise application programming , cbd ( component based software development ) becomes an effective way to increase productivity and quality of software for their distributiveness , high scalability , deployability , effectiveness and easy maintenance 集软件复用、分布式对象计算、 case (计算机辅助软件工程)和企业级应用程序开发等技术为一体的基于构件的软件开发以其分布性、高伸缩性、可配置性、高效性、易维护性等优点成为提高软件生产效率和产品质量的现实有效的途径。
Secondly , it dissertates the conception , class , and component models of software components technology as further development trends in this area . the crux of software reuse is consists of software architecture , domain engineering , software reengineering , open system technology , component based software development ( cbsd ) , and case technology 接着具体论述了作为软件复用的最新发展趋势的软件构件技术，介绍了软件构件的定义、分类、构件模型，以及支持软件复用的关键技术包括：软件构架、领域工程、软件再工程和开放系统技术、基于构件的软件开发( cbsd )和case技术等等。
