Today those technologies are used in such fields as user interface design , but are seldom applied in large project , and research on domain - specific application framework is still in the early phrase 目前这些技术在某些领域(如用户界面等)已得到一定应用，但是国内外大规模的应用项目尚不多见，而基于大粒度复用的应用框架的研究还处于起步阶段。
Recently , with the study on software reuse technology , software framework as a import reuse technology is now receiving more and more attentions . framework is a important approach to large - grained software reuse 近年来，随着软件重用技术研究的不断深入，软件框架作为一种重要的复用技术之一正日益受到人们的重视。框架是一种实现大粒度软件复用的有效途径。
We construct the whole application system with the big granularity pattern , and we design any layer and any part of the system with the little granularity pattern . con - pattern is a wrong or not good solution for an application 对于设计模式的研究与应用，应该在实际的应用系统中进行分析整理，仅仅是对大粒度模式的理论研究或者对小粒度模式的实现研究都是不够的。
These characteristics makes a great progress in the composite production of software . object - oriented framework is a kind of great granular component , it consists of many general components , and it specifies the collaboration among these components 对象框架可以看作一种大粒度的构件，其中包含若干个普通构件，定义了构件之间的协作规约，以实现一个大的系统功能。
The relationship between services and components is that enterprise - scale components large - grained enterprise or business line components realize the services and are responsible for providing their functionality and maintaining their quality of service 服务和组建之间的关系是，企业级的组件（大粒度的企业或者业务线组件）实现该服务并且负责提供它们的功能和维持它们的服务质量。
Aiming to software design of process analyzing apparatus , using the design philosophy of platform with framework as large - grained software reuse unit and components as small - grained software reuse units , the model of software reuse in scm is introduced and discussed 摘要软件复用是解决软件危机的有效途径，围绕气体分析仪表软件系统的设计，采用软件平台思想（大粒度框架复用和小粒度构件复用）开发了过程分析仪器的软件生成平台，用于生成其监控软件。
Component - based software technique is a mainstream in software reuse technique . as a big granularity component , framework provides base and context for the installing of component , which aims to resolve these challenges and to improve the efficiency and quality of software development 软件构件技术是一种软件复用技术中的主流技术，框架作为一种大粒度的软件构件，为构件的组装提供了基础和上下文，旨在解决软件系统开发所面临的困境，提高软件开发的效率和质量。
This frame can be the foundation of new development in these fields , realizing the reuse of the frame design in large granularity ; 3 . by analyzing and stat icing the wis , explicitly narrate the three common components , which have been used most widely , most effectively , and most worthy in this system 该框架可以作为领域内新系统的开发基础，在一定程度上实现大粒度的框架设计复用； 3通过对web系统的分析统计，对系统中使用范围最广、使用频率最高，使用价值最大的三类公共构件进行了详细的说明。
Firstly , we present the conception and technology of software reuse , then deeply discuss key technologies of software reuse such as software component technology , software architecture and domain analysis , etc , whose software component , i . e . software chip , is the main part of software reuse ; software architecture is software framework , which can been reused as software framework of a large granularity and higher abstract level and offers the fundament and the context for component integration ; domain analysis concentrates on a special application domain so that the generality of the design of software component is not considered in wide range , meanwhile its ratio of the reuse increases 本文首先叙述了软件复用的概念和软件复用技术，然后深入探讨了软件构件技术，软件体系结构和领域分析等软件复用中的关键技术，其中软件构件技术(即软芯片)是软件复用的核心；软件体系结构是软件的骨架，可以作为一种大粒度的、抽象级别较高的软件体系结构进行复用，并能够为构件的组装提供基础和上下文；领域分析使软件复用的目标集中在一个特定应用领域内，使构件的制作不需要在很广的范围内考虑其通用性，构件的复用率也相应增大。
The research of software development framework is the subject which is focused by software developers most . how to build a sturdy and stable framework is the aim of many software architecture experts . since the rise of software engineering , framework has become the basic of modern software development . the framework gives a new way for software reuse in big granular . and make the development more effective 软件开发框架的研究一直是软件开发者关注的课题。框架提供了大粒度软件复用的新途径,提高了软件开发的效率。因而如何设计并构建一个强健而稳定的框架一直是众多软件专家致力研究的目标。
