考虑了离散频率分布之间距离的测量问题。文中提出了三个条件，认为这三个条件反映了上述类型的距离度量所要满足的基本的、直观的要求，特别是参考遗传频率分布。这些条件主要涉及最大距离和线性方面。证明了只有一个函数满足这些条件，并且显式给出了这个函数，它具有度规的所有性质。
The problem of measuring distances between discrete frequency distributions is considered. Three conditions are stated, which are believed to reflect basic, intuitive requirements to be met by a distance measure of the above kind with particular reference to genetic frequency distributions. These conditions chiefly concern aspects of maximum distance and linearity. It is shown that exactly 1 function meets the conditions, and this function, having all properties of a metric, is explicitly given.
