Abstract: The Pt(100)/NO+CO system exhibits complex kinetic phenomena such as chemical oscillation and multisteady state when located far from the equilibrium. Applying the mathematical model suggested by Fink, we add periodic and stochastic perturbations on carbon monoxide partial pressure in computer simulation. The result shows stochastic resonance(SR) phenomena existing in two different regions. One is the traditional bistable region, the other is the coexistence of the oscillation with the stable state. Acontrast between SR phenomena in the two regions demonstrates that the two coexisting states vary considerably in their stability.
