论文摘要
我们分析研究了SEIR（易感暴露的传染性去除）流行模型。目的是为峰值和渐近值及其特征时间提供由COVID-19大流行影响的人群的简单分析表达式。
We analytically study the SEIR (Susceptible Exposed Infectious Removed) epidemic model. The aim is to provide simple analytical expressions for the peak and asymptotic values and their characteristic times of the populations affected by the COVID-19 pandemic.
