摘要
研究一类时滞三种群捕食-食饵扩散系统的持久性,利用微分方程比较原理,得到保证系统持久性的充分条件,并举例说明了其结果的可行性。
This paper studies the permanence of three-species predator-prey system with delay. By using the differential inequality theory, sufficient conditions which guarantee the persistence of the system are obtained. An example shows the feasibility of these results.
