針對事件的分布式程序調(diào)試過程中，需處理大量的事件消息，如果處理不當(dāng)，則會影響分布式程序的執(zhí)行，提出了一種分布式對象中的事件模型，采用這種模型，可以大大簡化事件消息的收集和處理，解決了分布式實時計算中的不確定性等問題，并降低了分布式調(diào)試過程本身給程序執(zhí)行的影響。

Abstract For the course of even-based distributed debugging, a great deal of event messages must be collected and handled. This process is not only complicated but also can disturbs the real execution of distributed program. This paper introduces an Object-Oriented event model ,which simplifies the collecting process of event message, makes it convenient to organize and manage the event message database, and adjuste indeterminacy，and reduces the disturbance of debugging to program execution.
Key words distributed debugging; object-oriented; event; replay; indeterminacy
