摘　　要：随机共振是非线性动力学系统中存在的一种现象,体现了噪声在非线性系统中的积极作用。我们首先阐述随机共振理论的基本概念和表征方法,然后在此基础上详细综述了生物系统中随机共振效应的研究进展和应用现状,最后对其提出总结和展望。Stochastic resonance （SR） is given to a phenomenon that is manifest in nonlinear systems whereby generally feeble input information can be amplified and optimized by the assistance of noise. First, the basic concepts and the characteristic quantities of SR are introduced in this paper. Second, SR in biological system and its applica- tions are reviewed in detail. At last, a summary is presented and the future researches on SR are prospected.
