basic reproductive number

基本解释

The basic reproductive number is found which determines the existence of the infection.
得到决定疾病灭绝和持续生存的基本再生数。
A two-strain SIR epidemic model is discussed and an explicit formula for the basic reproductive number is derived by analyzing the local stability of the trivial equilibrium.
讨论了一类由两种不同病毒导致的SIR流行病模型，分析了平凡平衡点的局部稳定性，得到了基本再生数的数学表达式；
When the basic reproductive number is not larger than 1, there only exists disease free equilibrium, otherwise, two equilibria, the endemic equilibrium and the disease free equilibrium exist.
当基本再生数大于1时，除存在无病平衡点外，还存在惟一的地方病平衡点。
