3) regeneration index
再生指数
4) reproduction constant
再生常数
5) regeneration times
再生次数
1.

6) basic reproduction number
基本再生数
1.
It was obtained that the basic reproduction number determining whether the disease becomes endemic.
通过假设被传染的易感者一部分经过一段潜伏期后才具有传染性,而另一部分被感染的易感者直接成为传染者,建立了一类带有非线性传染率的SEIR传染病模型,得到了确定疾病是否成为地方病的基本再生数以及无病平衡点和地方病平衡点的全局稳定性。
2.
The basic reproduction number is found by means of the next generation matrix.
借助再生矩阵求得了所建模型的基本再生数,并应用极限系统理论证得:当基本再生数不超过1时,模型仅存在全局稳定的无病平衡点;当基本再生数大于1时,无病平衡点不稳定,而且存在渐近稳定的地方病平衡点,当不考虑因病死亡率时,地方病平衡点是全局渐近稳定的。
