摘　　要：在带直接免疫的SIRS模型基础上,考虑疾病以2种途径进行传播.研究表明:流行病的传染阈值不仅与网络拓扑结构、直接免疫率、免疫丧失率和染病节点的传染能力有关,而且会受到2种传播途径在网络上的分布比例的影响.Epidemic transmission on complex networks via two distinct routes is considered based on an SIRS model with direct immunization. By theoretical analysis, the epidemic threshold is not only concerned with the topology of networks, direct immunization rate, loss rate of immunity and infective capability of infected individual, but also im- pacted by the ratio of two routes of spreading epidemic.

关 键 词：传染阈值 直接免疫 2种途径
