噪声对随机共振系统的影响至关重要。非线性系统在噪声与输入信号的协同作用下形成随机共振检测系统。若噪声过大，则噪声分布在高频，无法检测低频信号，噪声对系统起到消极作用；若信号过小，则在低频区的有用信号获得噪声提供的足够能量跨越非线性系统的势垒，小噪声的相对增加可以使系统的信噪比变小，对系统起到不利作用。通过研究噪声强度对随机共振系统影响，得到最佳噪声，降低检测信噪比。

The influence of noise on stochastic resonance system is crucial. Nonlinear systems under the synergy of noise to the in?put signal form stochastic resonance detection system. If too much noise, the noise distribution in high frequency, low frequency sig?nal cannot be detected, noise play a negative role to the system If the signal is too small, in the low frequency noise of useful signal get enough energy across a nonlinear system barrier, small relative increase of noise can make the system signal-to-noise ratio de?creases, have adverse effect on the system. By studying the noise intensity influence to stochastic resonance system, get the best noise, reduce the detection signal to noise ratio.
