摘要
考虑到某些动物有冬眠的习性,本文提出了食饵有冬眠习性的分段光滑的捕食-食饵模型,得到了平凡周期解全局稳定的条件.数值模拟表明,在一定的条件下,捕食者食饵将持续共存.
Considering that some animals hibernate,a predator prey system in which the prey hibernate is given in this paper,and the condition in which the trivial periodical solution is globally stable.Numerical simulations show that the predator and prey will coexist in some circumstances.
