传染者有常数存活率的种群动力学传染病模型
Communicable Disease Model of Species Mechanics of Communicator with Constant Survival Rate
【摘要】 运用Liapunov第二方法 ,对传染者有常数存活率 (易感染者有常数消除率 )的种群动力学传染病模型进行稳定性分析 ,同时研究了传染者 (易感染者 )的灭绝问题 .
【Abstract】 By using the second method of liapunov,the stability of the communicable disease model of species mechanics of communicator with constant survival rate were analyzed,and at the same time the extinct problem of communicator was studied.
