研究了两个参数同时受到随机干扰的一类SI传染病动力学模型
采用Fokker-Planck方程的方法
详尽的分析了该模型的动力学性质
而且得到了系统均衡解的均值和方差的显示表达式
从而该系统的的动力学行为就被完全弄清楚了.
We investigate an SI epidemic model with two stochastic perturbation. By using the FokkerPlanck equation method
the complete analysis of the asymptotic behaviour of the epidemic model is obtained. Moreover
the explicit expectation and variance of steady solution are also given. Thus
the statistic properties of dynamics of the model are completely clear.
