In parallel to PN, chapter 4 defines a series of concepts for timed PNs with weak firing rules , gives generative approaches for state reachable graph and state coverable graph, and proves that WTPN is equivalent to its underlying net about liveness, boundedness and reversibility.

第三章除简介PN的基本知识，还分析了现有的四种确定性时间约束PN与其基网系统之间关系，指出了它们用于定性分析和性能评估时出现的一些问题及其产生的原因，比较了它们的异同并指出了一些现存关于它们的模糊认识以及由此产生的不妥结论，基于此提出并初步探讨了四种LDTCPN模型与其基网系统的关系。

The results in this chapter improve and generalize some of the earlier foundings of IFDE with finite delay and infinite delay, therefore the applications are more extensive.In chapter two, we study the boundedness of system (1) mainly by the method of several Lyapunov functions containing partial components coupled with Razumikhin technique.

Prof. Long-Ruilin mentioned that if we want to study weighted inequalities for martingales, such as the maximal inequalities, the inequalities for the square operator and so on, the condition imposed on weights are mainly A〓 and S, but we don't know whether this condition is superfluous in all problems we consider. Since the condition can not be weakened for the known operators, now we consider a new operator to discuss its L〓-boundedness, then another problem arises, under what condition can we get it?

龙瑞麟先生曾经提到要讨论关于可测的鞅的极大算子、均方根算子以及条件均方根算子的L〓有界性，或它们之间的〓有界性时，所设的主要条件是A〓与条件S，有了这两个条件在讨论加权问题时基本上没有什么困难，但是要想用更弱的条件来代替它们，即使在古典情况下（此时S条件是自然满足的）也恐怕还不到时候。
