摘      要：The interplay between noise and nonlinearites can lead to escape *** nonlinear phe-nomena have been observed in various applications ranging from climatology to biology and *** reasons of computational ease,in most studies,Gaussian white noise is ***,this noise model is not physical due to the associated infinite energy ***,the authors present extensive experimental investigations and numerical simulations conducted to examine the impact of noise color on escape times in nonlinear *** a careful parameterization of the numerical simulations,the authors are able to make quantitative comparisons with experimental *** the experi-ments and simulations,it is illustrated that the noise color can drastically influence escape times and escape probability.
