详细研究了根据美国加利福尼亚州、日本、伊朗和智利的地震数据集构建的复杂地震网络的无标度和小世界特性。研究发现，在所有这些地理区域中，当小区大小（即构建网络所需的粗粒度规模）变得大于某个值时，幂律连通性分布的指数 gamma 和聚类系数 C 分别取通用不变值 gamma a 千分之 1 和 Ca 千分之 0.85。对于这种显着的不变性的出现，给出了可能的物理解释。
The scale-free and small-world properties are studied in detail for the complex earthquake networks constructed from the seismic data sets taken from California (USA), Japan, Iran and Chile. It is found that, in all these geographical regions, both the exponent gamma of the power-law connectivity distribution and the clustering coefficient C take the universal invariant values gamma a parts per thousand 1 and Ca parts per thousand 0.85, respectively, as the cell size, which is the scale of coarse graining needed for construction of network, becomes larger than a certain value. A possible physical interpretation is given to the emergence of such remarkable invariance.
