图G的Wiener极性指数是指图G中使得u和v之间的距离等于3的无序顶点对{u，v}的个数。本文研究了具有一定数目甲基的烷烃分子图的最大Wiener极性指数。
The Wiener polarity index of a graph G is the number of unordered pairs of vertices {u,v} of G such that the distance between u and v is equal to 3. In this paper, the maximum Wiener polarity index of molecular graphs of alkanes with a given number of methyl groups is studied.
