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.
对第一和第三个模型还给出了R_0>1对地方病平衡点的存在唯一性。
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，无因病死亡时，极限方程的惟一地方病平衡点是全局渐近稳定的。
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.
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。
