摘　　要：提出一种基于SF网络具有Logistic阻滞增长特性的演化网络模型。研究在不同的网络最大容纳量和增长速率情况下,网络拓扑性质的变化,获得网络最大容纳量和增长速率影响网络度分布、平均路径长度、聚类系数及同配系数等拓扑特性的规律。数值拟合结果表明,提出的Logistic阻滞增长网络模型具有双幂律分布特性和异配性。Based on the growth of nodes in scale-free network,a new evolving network model with logistic hindering growth is proposed,and the inherent mechanisms of environmental capacity and growth rate affecting some main topological properties,such as degree distribution,average shortest path length,clustering coefficient,and assortativity coefficient,are investigated in logistic hindering growth mode.Theoretical and numerical results show that the new network model has some typical characteristics of complex network,including bilateral power-law degree distribution,and disassortativity.
