摘要:

利用比较定理给出了具有时滞的捕食被捕食模型的有界性和一致持久性的充分条件, 利用Matlab软件给出了种群模型的数值模拟结果.

关键词: 时滞; 持久性; 种群

Abstract:

The sufficient conditions for the persistence and bound of a preypredator system with time delay were obtained via the comparison theorem. The numerical simulation result of population model was obtained with the Matlab software.

Key words: time delay; persistence; population
