摘要 考虑了一类双营养条件下带时滞的捕食chemostat模型 .利用Liapunov泛函方法和Razu mikhin方法 ,得到了食饵种群一致持续生存 。 A predator prey chemostat model with two nutrients and delay, is discussed. Based on the methods of Liapunov functionals and the technique of Razumikhin, this paper obtains the sufficient conditions for permanence of prey population and extinction of predator population.
