常見例句雙語例句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(diǎn)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(diǎn)是全侷漸近穩(wěn)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(shù)大於1時,除存在無病平衡點(diǎn)外,還存在惟一的地方病平衡點(diǎn)。 返回 endemic equilibrium
