摘要

我们研究了噪声对一个简单的捕食-捕食模型的影响，其中振荡是由系统的内部动力学触发的，而没有任何外部周期性驱动的帮助。我们报告了在没有外部驱动的情况下，该系统中没有阈值或势垒的随机共振行为的发生。

Stochastic resonance without an external periodic drive in a simple prey-predator model

We have investigated the effect of noise on a simple prey-predator model where the oscillations are triggered by the internal dynamics of the system without the aid of any external periodic drive. We report the occurrence of stochastic resonancelike behavior in this system, which does not have a threshold or a potential barrier, in the absence of an external drive.
