研究了一类具有潜伏期的无免疫型传染病动力学模型,用摄动理论讨论分析了相应的非线性系统,得到了不同群体生存变化的渐近表达式,从而揭示了各种作用对不同群体生存影响的规律.本文的研究为解决一些类型的非线性模型提供了一种有效的方法.
A kind of latent immune model of non-immune infectious disease was studied. The perturbation theory was used to analyze and analyze the corresponding non-linear system. The asymptotic expressions of the survival of different groups were obtained, which revealed that various effects on different groups The law of survival impact.The research in this paper provides an effective method to solve some types of nonlinear models.
