摘要
考虑一类时滞三种群捕食—食饵扩散系统的持久性,应用微分方程比较原理,得到保证系统持久性的充分条件,并推广了相应文献的主要结果.
The permanence of three - species predator - prey system with delay and Holling type function- al response was considered. By using the differential inequality theory, sufficient conditions which guarantee the persistence of the system were obtained. The results generalized the main result of some former work.
