研究了具有标准发生率且对易感者和新生儿进行预防接种的SIR传染病模型，得到了无病平衡点和地方病平衡点全局渐近稳定的条件，基于Lyapunov方法设计了控制器，给出无病平衡点全局渐近稳定的条件。%The SIR epidemical model with standard incidence and continuous vaccinations for the infective and the news are discussed .The conditions for global asymptotical stability of the disease -free equilibrium and the endemic equilibrium are obtained.Further, the conditions for global asymptotical stability of the disease -free equilibrium are given by establishing controller based on Lyapunov method .
