摘要： 讨论当前构件模型在移动分布式环境中的缺陷，在此基础上，将反射技术与软件契约式设计思想相结合，提出一种在移动分布式环境下具有上下文感知功能的可信构件模型——MDETCM，并对其进行描述。给出该模型的具体实例，并对其进行性能测试，结果表明，构件执行任务的成功率得到提高。

Abstract: Discussing the deficiency of component model for mobile distributed environment currently, this paper presents a context-aware component model, Mobile Distributed Environment Trusted Component Model(MDETCM), for mobile distributed environments with combining reflection and software-contact technology. It gives a concrete instance of this model and conduct performance test. Results show that the success rate of task implemented by component is enhanced.

Key words: mobile distributed environment, trusted component model, reflection
