We reconsider the moment analysis of the Bak-Tang-Wiesenfeld and the stochastic sandpile model introduced by Manna [J. Phys. A 24, L363 (1991)] in two and three dimensions. In contrast to recently performed investigations our analysis reveals that the models are characterized by different scaling behavior, i.e., they belong to different universality classes.
我们重新审视了二维和三维空间中Bak-Tang-Wiesenfeld模型以及Manna提出的随机沙堆模型[《物理学报A》24,L363 (1991)]的矩分析。与最近进行的研究不同,我们的分析表明,这些模型具有不同的标度行为,即它们属于不同的普适类。
