噪声和非线性之间的相互作用会导致逃逸动力学。相关的非线性现象已经在从气候学到生物学和工程学的各种应用中被观察到。由于计算方便，在大多数研究中都使用高斯白噪声。然而，由于相关的无限能量含量，该噪声模型不是物理的。在这里，作者提出了广泛的实验研究和数值模拟，以研究噪声颜色对非线性振荡器中逃逸时间的影响。通过对数值模拟的仔细参数化，作者能够与实验结果进行定量比较。通过实验和仿真表明，噪声颜色对逃逸次数和逃逸概率有很大的影响。
The interplay between noise and nonlinearites can lead to escape dynamics. Associated nonlinear phenomena have been observed in various applications ranging from climatology to biology and engineering. For reasons of computational ease, in most studies, Gaussian white noise is used. However, this noise model is not physical due to the associated infinite energy content. Here, the authors present extensive experimental investigations and numerical simulations conducted to examine the impact of noise color on escape times in nonlinear oscillators. With a careful parameterization of the numerical simulations, the authors are able to make quantitative comparisons with experimental results. Through the experiments and simulations, it is illustrated that the noise color can drastically influence escape times and escape probability.
