按Logistic增长且具有连续预防接种和潜伏期密度依赖的SEIRS流行病模型

An Density-dependent Latent Peroid SEIRS Epidemic Model with Logistic Birth Rate and Continuous Vaccination

本文在种群按Logisti增长情况下研究了预防接种和潜伏期密度依赖对SEIRS流行病模型的影响,得到了无病平衡点和地方病平衡点的存在性以及稳定性条件.

In this paper, we consider the influence of continuous vaccinations and density-dependent latent peroid on an SEIRS epidemic model with Logistic birth rate . We get the condition of the existence and stability of disease-free stable point and disease stable point.
