Abstract
The effects of noise on phase synchronization (PS) of coupled chaotic oscillators are explored. In contrast to coupled periodic oscillators, noise is found to enhance phase synchronization significantly below the threshold of PS. This constructive role of noise has been verified experimentally with chaotic electrochemical oscillators of the electrodissolution of Ni in sulfuric acid solution.
摘要
研究了噪声对耦合混沌振荡器相位同步（PS）的影响。与耦合周期振荡器不同，发现噪声在显著低于相位同步阈值时能显著增强相位同步。噪声的这种建设性作用已通过硫酸溶液中镍电溶解的混沌电化学振荡器进行了实验验证。
