摘　　要：研究了基于信息老化效应和辟谣措施的网络谣言传播模型,提出了具有阶段结构且更符合实际谣言传播过程的SIKR_AGING模型.并做了稳定性分析,进一步对在社会均匀网络中的各状态人数变化趋势进行了数值仿真.结果表明,信息老化速率和辟谣力度及时效在谣言传播过程中起到了重要作用,信息老化速率越快、辟谣力度越大、辟谣时间越早则谣言的社会影响力越小.为相关职能部门控制舆情提供参考.The network rumor spreading model with information aging effects and counter-rumour measures was studied. The SIKRAGING model with stage structure and more consistent with the actual rumor propagation process was proposed and the stability analysis was made. The numerical simulation for the changing trend of the number of states in networks was carried out. The results of simulation showed that the rate of information aging,counterrumour efforts and counter-rumour time play an important role in the process of rumor spreading. The faster the rate of information ages,the greater the efforts of counter-rumour and the earlier of counter-rumour time will makes the rumor＇s social influence smaller. Additionally,this paper provided reference for the relevant departments to control public opinion.
