摘　　要：适应性构件应具备灵活应对功能需求变化的能力。为使构件支持这一特性,本文研究设计给出构件行为动态重构功能模型及其交互逻辑模型,并基于动态代理机制实现该模型,通过重构构件的行为实现构件执行功能的转换,从而使构件可灵活适应功能需求的变化。最后的实例开发实验证实了这种设计实现方式的可行性以及行为重构的有效性。Adaptive component should be able to flexibly adapt to function requirement changes. In order to support this characteristic we design and provide a component behavior restructuring function model and an interaction logic model, then we implement the models based on dynamic proxy mechanism, and so we implement function transition for a component by dynamically restructuring its behavior and enable the component to flexibly adapt to function requirement changes. At last, an example development experiment shows that the designed models are effect and the implementation approach is feasible and effective.
