本文中提出了一种电子邮件网络加权动态演化模型,它通过生成和删除两种机制来模拟用户定期整理其地址簿的行为，模拟了真实电子邮件网络拓扑结构的动态演化。并通过仿真实验研究了不同演化机制对该网络中3 个重要的属性的影响。关键词: 电子邮件；加权网络；演化模型；无尺度网络Abstract: Through two evolution principles as generation procedure and deletion procedure, new links are generated and existing links are deleted. It models users’ behaviors of managing their address books periodically, and the evolution of the topology of email network in the real-world. A comprehensive set of simulations have been carried out to investigate the effects of different evolution principles on the structure of the network model.Key words: E-mail; weighted network; evolving model; scale-free networks
