论文摘要
在本文中，引入了确定性SIR模型的关键社区规模（CC）的概念，并强调了其对疾病动态的后果。爆发后这种疾病会消失。竞争排斥的原则也不再正确。这是两个竞争病毒菌株的动力学的例证。可以从人群中消除具有较高R0的病毒。
In this paper the concept of Critical Community Size (CCS) for the deterministic SIR model is introduced and its consequences for the disease dynamics are stressed. The disease can fade out after an outburst. Also the principle of competitive exclusion holds no longer true. This is exemplified for the dynamics of two competing virus strains. The virus with higher R0 can be eradicated from the population.
