具有投放率和食饵扩散的非自治捕食模型的持久生存性

摘要

研究了一类具有投放率和食饵扩散的非自治捕食系统，利用变量代换和函数单调性等相关理论证明该系统在一定条件下是持久生存的．%A nonautonomous predator-prey system with diffusion of prey and invest rate is researched. It is proved that the system is persistent under suitable condition by correlation theory of variable substitution and monotony of function etc.
