1) a seed pulse
种籽脉冲
2) impulsive vaccination
脉冲接种
1.
In this paper,we establish a kind of new class age-structure SEIR epidemic model with impulsive vaccination and nonlinear infectivity,which contains ODEs and PDEs at the same time.
建立了一类新的带有脉冲接种的类年龄结构SEIR流行病模型,并考虑其具有非线性传染率。
2.
In this paper,considering impulsive vaccination strategies of SIR epidemic models with incidence rates.
研究了具有感染率为βIS/(1+R)流行病SIR模型的脉冲接种策略,通过利用频闪映射的方法,得到了无病周期解的确切表达式,并且也给出了此周期解的全局稳定性分析,即如果R<1,疾病得以根除,无病周期解稳定,如果R>1,则疾病持续,无病周期解是不稳定的,疾病流行。
3) pulse vaccination
脉冲接种
1.

该模型充分考虑了传染病的扩散函数、脉冲接种的周期、应急救援中心与灾害发生点的距离,以及应急救援中心的建设和维护费用等多个因素的约束。
3.
The application example of optimization pulse vaccination is given.
利用时滞系统的脉冲优化原理对该类模型进行分析,阐述了脉冲优化控制的基本原理和实现方法,并给出了优化脉冲接种的应用实例。
