摘要
自然界与社会生活中存在各种各样性质迥异的幂律分布现象,因而对它们的研究具有广泛而深远的意义.近年来,借助于有效的物理和数学工具以及强大的计算机运算能力,科学家们对幂律分布的本质有了进一步深层次的理解.文章从统计物理学的角度,简要介绍了幂律分布的研究史以及最新的进展,并对它的形成机制及动力学影响作了一些简要的阐述.
Various phenomena governed by power law distributions are ubiquitous in nature and society, thus their study carries broad and far-reaching significance. In recent years, by effective physical and mathematical tools and powerful computational faculties, a deeper understanding of the essence of these distributions has emerged. We review briefly the history and current development of research on power law distributions from the perspective of statistical physics, and present a concise discussion of the mechanisms of their generation and their influence on certain dynamic properties.
