生物医学领域中随机共振的理论及应用研究

Research on the theory and application of stochastic resonance in biomedical field

随机共振是非线性动力系统中的普遍现象，它向人们展示了噪声在非线性体系中的积极作用。除了经典的随机共振理论外，还讨论了其他类型的随机共振，诸如非周期、超阈值和耦合随机共振等等；讲述了随机共振的基本机理及表征方法；介绍了随机共振在生物和医学领域中的应用及最新研究进展，并对随机共振的发展前景做了展望。

Stochastic resonance is a phenomenon manifested in nonlinear systems whereby generally feeble input information can be amplified and optimized by the assistance of noise. The mechanism and classical theory of stochastic resonance are introduced in this paper. Meanwhile, several kinds of stochastic resonance with characteristic quantities that are important to quantify stochastic resonance are presented. Applications in biomedical field are described in detail. Foreground of the research in experiment and application are reviewed in this paper.
