我们引入了一个能够重现1/f噪声主要特征的模型：超普适性（幂律指数与系统维度无关；我们在此展示了d = 1、2时的结果）以及功率谱中明显缺乏低频截止。该模型的基本要素是激活 - 失活过程和耗散。[S0031 - 9007(98)08193 - 9]
We introduce a model able to reproduce the main features of 1/f noise: hyperuniversality (the power-law exponents are independent on the dimension of the system; we show here results in d = 1, 2) and apparent lack of a low-frequency cutoff in the power spectrum. Essential ingredients of this model are an activation-deactivation process and dissipation. [S0031-9007(98)08193-9].
