主 题:non-Gaussian colored noise catalytic reduction of NO with CO on Pt(100) reaction rate oscillation coherence resonance
摘 要:The effect of the non-Gaussian colored noise(NGN) on the dynamics of nonlinear systems has attracted increasing *** work numerically studied the effect of a particular kind of the NGN,mainly in terms of its departure from Gaussian noise,on the rate oscillations(RO) in the catalytic reduction of NO with CO on Pt(100) *** was found that power spectrum density changes non-monotonically and the signal-to-noise ratio shows several peaks with increasing departure,demonstrating the presence ofdeparture-induced multiple resonance.Since the departure of the NGN determines the probability distribution and hence denotes the type of the noise,the phenomenon ofdeparture-induced multiple resonancenot only gives multiple enhancements of the RO by virtue of the departure of the NGN,but also implies that,besides Gaussian noise,various other types of noise may enhance the RO in the surface catalytic reaction systems.
