摘要
为促进复杂网络和传染病动力学在传染病研究中的应用,分析了SF(无标度)网络的拓扑结构对传染病传播的影响,深入讨论了SIR(易感者-染病者-康复者)模型的传播规律并得到基本再生数R0.为了进一步控制疾病的传播,采取目标免疫策略,得到了有限的基本再生数Rt0.
In order to study the application of complex network and infectious diseases dynamics in the research of diseases,we investigate the effects of scale-free networks' topological structure on the spread of diseases,analyze the SIR(susceptible-infected-recovered) epidemic model on scale-free networks and get the basic reproduction number R0.To control the diseases,the target immunization scheme is taken and the finite basic reproduction number R0t is obtained.
