摘要：

In this paper, the phenomenon of stochastic resonance in an asymmetric bistable system with time-delayed feedback and correlated noises is investigated. The explicit expression for signal-to-noise ratio is obtained under the condition of small time delay approximation and adiabatic approximation. The effects of the delay time,the noises correlation and the static asymmetry to the signal-to-noise ratio are discussed.
