摘要
研究了一类食饵具有阶段结构的时滞捕食系统,通过分析相应的特征方程,得到非负平衡点的局部稳定性,利用比较原理和迭代法得到平衡点的全局渐近稳定的充分条件.最后,通过数值模拟阐述了所得结论的正确性.
This paper studies a delayed predator-prey system with stage structure for prey.By analyzing the corresponding characteristic equations,the local stability of the nonnegative equilibria is obtained.The sufficient conditions of the global asymptotic stability of the equilibria are investigated by using the comparison principle and an iteration technique.Finally,numerical simulation describes the conclusions are correct.
