本文总结了现有被动对象模型存在的不足，探讨了对象的动态行为的抽象和描述问题，提出并建构了基于事件驱动的主动对象模型．在该模型中，引入了主动对象，主动对象能检测到外部发生的事件以决定自己的行为；引入主动对象类，以对主动对象进行抽象描述；还引入了运作对象，以协调其他主动对象的行为，一个运作对象还代表了一个可运行的系统，可以通过继承复用已开发的系统，增加了继承的力度．
This paper summarizes the existing problems of the existing passive object model, explores the abstract and description of the object’s dynamic behavior, and proposes and constructs an active object model based on the event-driven. In this model, active objects are introduced. Active objects can detect external events to determine their own behavior. Active objects are introduced to abstract the active objects. Operational objects are also introduced to coordinate other active objects Behaviors, an operational object, also represent a workable system that increases the degree of inheritance through the inheritance of reused developed systems.
