摘要

本文研究了非等温条件下的一阶不可逆放热反应。它是最简单的系统之一，能够表现出复杂的行为，如多稳定性、振荡和滞后。我们研究了该系统在存在外部驱动和噪声的情况下，在系统显示双稳态的区域。我们证明了随机共振现象，其特征是在最优噪声存在下系统对弱周期驱动的响应增强。

Stochastic resonance in an exothermic irreversible reaction

In this article, we study a first order irreversible exothermic reaction under nonisothermal condition. It is one of the simplest systems capable of showing complex behaviour like multistability, oscillations and hysteresis. We have investigated this system in the presence of external drive and noise in the region where the system shows bistability. We demonstrate the phenomenon of stochastic resonance characterized by an enhancement of response of the system towards weak periodic drive in the presence of optimal noise.
