basic reproductive number

基本解释

The basic reproductive number is found which determines the existence of the infection.
得到決定疾病滅絕和持續生存的基本再生數。
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.
討論了一類由兩種不同病毒導致的SIR流行病模型，分析了平凡平衡點的侷部穩定性，得到了基本再生數的數學表達式；
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.
儅基本再生數大於1時，除存在無病平衡點外，還存在惟一的地方病平衡點。
