中文摘要: 以存在凝胶化现象的高分子反应模型为背景,定义了高分子反应所对应的可逆Markov过程,给出了过程的稳定分布及配分函数,推导出了分子间协方差的表达式.通过对该过程在下临界、临界、上临界状态下的渐近性质的分析,证明了仅在临界状态下系统存在长程相关性.
Abstract:A reversible Markov process as a chemical polymerization model where a gelation transition exists is presented.The stationary distribution,partition function and expression of covariance of this model are obtained.The asymptotic behavior of the process in subcritical,critical,and supercritical stages is studied.It is proven that only in the critical stage there exists a long term correlation.
