摘要
本文研究一类非自治具有Holling Ⅳ类功能性反应和时变时滞的捕食者-食饵系统的持久性,利用比较定理结合微分不等式的一些分析技巧,得到了保证系统永久持续生存的新的充分条件,并且推广和改进了已有文献的一些结果。
The persistence of a non- autonomous predator- prey system with HoUing Ⅳ- type functional response and time - varying delay is studied. By applying the comparative theorem combining some analytical technique about differential inequality, some new sufficient conditions for guaranteeing the permanence of the system are obtained which extend and improve the results obtained in the literature.
