中文摘要：

为了向分布式实时嵌入式系统（DREs）的运行过程提供可信保障服务，方便上层应用程序的开发，提出了一种针对DRES的可信构件服务模QUOCCM。该模型将系统功能实现与性能确保分离开，把应用程序的性能确保模块抽象成通用的服务确保构件，为运行于动态环境下的应用程序提供自适应的可信保障服务。该文以一个模拟实现的飞行控制系统验证了QUOCCM模型的可行性和灵活性。

英文摘要：

To provide credible services and facilitate the development of applications for the distributed real-time embedded system （DRES）, a credible service component model, QUOCCM, is proposed. By QUOCCM, a DRES application is separated into two parts： function realization and performance guarantee. The latter is encapsulated into some components to provide common services for the former. Specially, QUOCCM can provide an adaptive service support about application performance running in the dynamic environment. Finally, a flight control system in DRES has been used to confirm the feasibility and flexibility of the model.
