摘 要：Effects of time delay on stability of an unstable state in a time-delayed bistable system are *** analytic expression of the transition rate W(x_(u),τ)from unstable state xu to stable state x+is *** numerical calculation results of W(x_(u),τ)indicate that W(x_(u),τ)decreases with the increasing multiplicative noise intensity,the additive noise intensi by and the strength of correlations between the multiplicative and the additive noise increase,but W(x_(u),τ)increases with increasing delay ***,the multiplicative noise,the additive noise and the correlations between the multiplicative and the additive noises enhance the stability of the unstable state in the time-delayed bistable system but the stability is weakened by time delay.
