A PROPERTY OF THE RANK‐SIZE DISTRIBUTION AND ITS USE IN AN URBAN HIERARCHY CONTEXT
证明了经典等级规模分布关于任意城市的对称性，并利用该性质刻画了城市规模围绕等级中位数的分布特征，包括对称性、离散度上界和规则间距。
ABSTRACT This paper proves the symmetry of the classical rank‐size distribution with respect to any city according to a criterion of relative population difference. This property is used to characterize the distribution of city sizes around the median center of their hierarchical level by the existence of symmetry, of an upper bound to dispersion, and of a regular spacing. An interpretation is suggested.
