【Abstract】 Based on the model which was put forward by SANCHEZ,the stochastic resonance phenomena in the field-driven and spin-like model on Small-World network with directed links were investigated.It was found that the double stochastic resonance peak can appear whether the system shows the continuous phase transition or first-order phase transition.更多还原
