摘要: 研究含有免疫作用的易感染者-感染者-移出者传染病模型(SIR模型)在复杂网络上的动力学行为.首先考虑具有齐次性质的复杂网络(度分布服从指数分布)中免疫作用对疾病传播的影响,然后讨论具有非齐次性质的复杂网络(度分布不服从指数分布,如幂分布)中免疫作用以及非齐次性质对疾病传播的影响.

Abstract: This paper studies the dynamic behavior of SIR epidemic model with immunity on complex networks. First, effects of immunization on the spread of epidemic on homogenous networks in which the node degrees obey an exponential distribution are considered. The effects of immunization and the quality of heterogeneous on the spread of epidemic in heterogeneous networks, in which the node degrees satisfy a powerlaw distribution rather than the exponential distribution, are then discussed.
