endemic equilibrium

基本解释

For the first and the third model, it is also proved there exists an unique endemic equilibrium when R_0>1.
對第一和第三個模型還給出了R_0>1對地方病平衡點的存在唯一性。
Specially, if the death rate due to disease equals zero, the sole equilibrium point of the limit equation for endemic is asymptotically stable in global field.
特殊地，無因病死亡時，極限方程的惟一地方病平衡點是全侷漸近穩定的。
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。
