Af型自由基均聚反应的固化理论(Ⅱ)——凝胶网络的结构参数

用高分子反应统计理论,给出A_f型自由基均聚反应在不同反应程度时的弹性有效链及悬吊链的链数、链节数和平均链长,也得到了体系的有效交联点数和弹性模量,进而给出弹性有效链的数量和重量分数,以此可进一步揭示该反应体系凝胶网络的粘弹性及相关的力学性质.     

The Elastic Continuum Limit of the Tight Binding Model

The authors consider the simplest quantum mechanics model of solids,the tight binding model,and prove that in the continuum limit,the energy of tight binding model converges to that of the continuum elasticity model obtained using Cauchy-Born rule.The technique in this paper is based mainly on spectral perturbation theory for large matrices.
