摘　　要：在经过4年之久的修订过程之后,OMG通过并采纳了UML2.0.其中,UML的扩展机制是在UML2.0的提案需求中提出要做重大修订的部分之一.为了能够迅速了解UML引入扩展机制的必要性、UML1.X中扩展机制存在的问题以及UML2.0中扩展机制的新动向,分析了UML2.0扩展机制的必要性以及修订的原因,简要介绍了UML2.0的两种扩展机制,即一阶扩展机制(基于元模型的扩展机制)和轻量级的扩展机制(基于外廓的扩展机制),以及两种扩展机制的比较.最后对UML2.0的扩展机制进行简要的评述与展望.After a revision with a period of four years,OMG voted and adopted the specifications of UML 2.0. On the observation of the revision,the extension mechanism is one of the most important parts revised.In order to clarify the necessity of introducing the extension mechanism into UML and the existing problems of the mechanism in UML 1.X, as well as to help people know the tendency of the work in UML 2.0,the background and rationales of the revision are analyzed and the development of two extension mechanisms in UML 2.0 is illustrated,i.e. one is first-class extension mechanism (extension based on meta-models); the other is light weight extension mechanism (extension based on Profiles).Then the comparison between the two mechanisms is presented.Finally,the applicable vision of the improved extension mechanism of UML 2.0 is predicted.
