研究一类非单调功能反应和周期常数脉冲扰动的三种群捕食-食饵系统,得到了系统灭绝与持续生存性的充分条件,并利用脉冲微分方程的Floquet理论和比较定理对相关定理进行了证明。
The three-specise predator-prey system with non-monotonic functional response is considered under the interference of periodic impulse,sufficient conditions for the system to be extinct and permanence are given, and relevant theorems are established and proved by the impulse comparison theorem and Floquet theorem.
