描述了一种基于苯系系统 B 的基本割断的超维纳指数 (WW ) 的计算方法。一对基本割将 B 的顶点划分为四个片段，拥有 nrs , r, s = 1, 2 个顶点。 WW 等于 n11 n22 + n12 n21 形式的项之和。通过推导晕晕/环晕晕系列WW的通用表达式说明了该方法的适用性。
A method for the calculation of the hyper–Wiener index (WW ) of a benzenoid system B is described, based on its elementary cuts. A pair of elementary cuts partitions the vertices of B into four fragments, possessing nrs , r, s = 1, 2 vertices. WW is equal to the sum of terms of the form n11 n22 + n12 n21 . The applicability of the method is illustrated by deducing a general expression for WW of the coronene/circumcoronene series.
