结合我国奶牛布鲁氏菌病的现状以及疾病自身的特点
考虑环境当中病菌项的传染
分析并建立了具有外界引入以及剔除等措施的奶牛布鲁氏菌病动力学模型.从理论上求出了系统的基本再生数
分析了各平衡点的存在性和局部稳定性.通过谱半径方法以及构造适当的Lyapunov函数证明了无病平衡点和唯一的正平衡点全局渐进稳定.
Combining the current situation of Dairy cattle brucellosis in our country with Brucellosis own characteristics
and Considering the bacteria infection of the environment
the Dairy cattle brucellosis dynamical model was formulated with outer importing and excluding measures.The basic reproductive rate was calculated theoretically.The existence of equilibrium points and local stability were analyzed theoretically.By using the method of spectral radius and constructing appropriate Lyapunov functions
it draws the conclusion that the disease-free equilibrium and the unique endemic equilibrium are global asymptotic stability.
