摘要：

Petri 网进程是对Petri 网并发语义的一个刻画，是Petri 网分析和验证的有效手段. 该文针对有界Petri 网研究进程表达式和活性性质之间的关系，给出了基于进程表达式的有界Petri 网及其同步合成网的活性判定定理. 同时研究了进程表达式与虹吸、陷阱间的关系，是Petri 网活性研究的一个新的尝试.

关键词: Petri 网, 进程表达式, 活性, 陷阱, 虹吸

Abstract:

 Process of Petri nets can present the concurrent semantic of Petri nets, which is an effective way for
analyzing and verifying the Petri net properties. This paper studies the relationship between process expression
and liveness of bounded Petri nets, and provides theorems of liveness determination for bounded Petri nets
and their synchronous composition nets. The paper also explores the relationship between process expressions
and traps and siphons.

Key words: Petri nets, process expression, liveness, trap, siphon
