摘要
考虑一类食饵种群具有阶段结构和捕食者种群具有阶段结构与时滞的两种群捕食系统 .分析了系统的非负不变性、边界平衡点性质及全局渐近稳定性 .在这个系统中 ,随着时滞的增加 ,时滞能引起稳定性。
A system of retarted functional differential equation is proposed as a predator-prey model with stage structure in the prey.Mathematical analyses of the model equations with regard to invariance of non-negativity,nature of equilibria and global stability are analyzed.It is shown that in this model the time delay can cause a stable equilibrium to become unstable.
