摘要翻译:
针对不同的人群结构,分析了一种传染病的传播模型。种群内部的相互作用由小世界网络描述,范围从有序格到随机图。对于更有序的系统,有一个波动的低感染的地方病状态。在网络无序的有限值下,我们发现在感染子种群的大小上有一个向自我持续振荡的转变。

英文摘要:
A model for the spread of an infection is analyzed for different population structures. The interactions within the population are described by small world networks, ranging from ordered lattices to random graphs. For the more ordered systems, there is a fluctuating endemic state of low infection. At a finite value of the disorder of the network, we find a transition to self-sustained oscillations in the size of the infected subpopulation.
