摘　　要：上下文相关技术已经成为普适计算环境中用于应用服务的不可或缺的核心技术之一。对于基于构件的中间件来说,对高性能的上下文管理的需求更是必不可少,因为它构成了普适计算环境中构件适配和部署的重要基础。因此,在已有构件中间件的基础上,我们针对普适计算环境的特点提出了一种整体的上下文管理方法,将上下文管理集成在已有的构件化中间件中。应用表明,该方法能够更好地支持普适计算环境下上下文相关的构件化应用开发。The context-awareness has become the one of core technologies for application services in ubiquitous computing environments and is considered as the indispensable function for ubiquitous computing applications. The need for highquality context management is evident to the component-based middleware for it forms the basis of the component adaptation and the component deployment in pervasive computing. Therefore, we suggest a holistic approach in which context management is an integral part of a more comprehensive adaptation middleware, thus enabling the development and support of context-aware, component-based applications.
