一类病毒自身发生变异的传染病模型的近似解
The Approximate Solution of an Epidemic Model with Virus Auto Variation
【摘要】 针对一类病毒变异前后传染病患者具有不同传染率的情形,利用同伦映射方法,得到其相应分阶段传播的动力学生态模型的渐近解.
【Abstract】 According to the differential incidences for the early virus and terminal virus patients,an epidemic model with stage-structure is considered.By using the homotopic mapping method,the approximate solution of the dynamic ecological model is obtained.
