摘　　要：为了考虑意见领袖对谣言传播过程的影响,在传染病模型ISR的基础上,构建考虑冬眠者被领袖传播者唤醒的微博谣言传播模型,给出相应的平均场方程,并对其分析求解出谣言的传播阈值,利用MATLAB对模型进行数值仿真和结果分析。模拟结果表明:在谣言传播过程中,由于唤醒机制的作用,使得谣言的最终影响力增大,加快了谣言结束时间。政府部门及微博谣言控制部门可通过对微博中意见领袖的博文进行监督,尽量避免意见领袖有意或无意参与到谣言传播中来,降低谣言传播对公众及社会造成的影响。In order to consider the influence of opinion leaders on rumors spreading process,on the basis of the infectious disease model ISR,the paper built micro-blog rumors spreading model that considering hibernation was awaken by opinion leaders,gave corresponding average field equations,and analyzed it find the threshold of the spreading of rumors,using MATLAB to the results of numerical simulation and analysis of the model. Simulation results showed that in the process of rumor spreading,due to the wake up mechanism,the rumors influence eventually increases,accelerate the rumor over time. Government departments and micro-blog rumors control department can supervision over the post through the opinion leaders and try to avoid opinion leaders consciously or unconsciously involved in the rumor spreading,reduce the impact of spreading rumors on the public and the society.
