摘　　要：基于中间件的构件运行支撑平台是实现基于构件的软件复用的关键.现有中间件技术侧重于解决大多数领域开发分布系统均会遇到的共性问题,忽视了单个应用领域内的共性问题.在下一代中间件技术追求的主要特性中,开放性与灵活性能够有效增强中间件对领域特性的支持.本文介绍了一个开放、灵活、面向领域的构件运行支撑平台,重点研究了平台内核、可扩展互操作框架以及元编程机制,并结合电力领域探讨了面向领域的定制与扩展方法.The critical challenge to component-based software reuse is the component operating platform based on middleware. The existing prevalent middleware has focused on the common problems in the development of distributed systems in almost every application domain,but ignored the commonality in a given domain.The openness and flexibility, which are the well-recognized important characteristics of next generation middleware, can enhance middleware of supporting the domain-orientation much more. This paper presents an open, flexible and domain-oriented component operating platform, called PKUAS. This paper describes the micro kernel interior of the platform,interoperability framework and the meta-programming mechanism in detail. Moreover, this paper studies how to customize and extend PKUAS for the electric power systems.
