| Abstract: | The asymmetric effects on the escape rates from the stable states x± in the bistable system are analyzed. The results indicate that the multiplicative noise and the additive noise always enhance the particle escape from stable states x± of bistable. However, the asymmetric parameter r enhances the
particle escape from stable state x+, and holds back the particle escape from stable state x-. |
