对于一个简单连通无向图G而言,其Szeged指标被定义为Sz(G)=∑e,这里u, v∈V(G), e=uv, neu表示图G中到点u的距离小于到点v的距离的点数, nev的定义类似。S. Yousefi给出了R型环状纳米管TUC4C8(R)的Wiener指标的计算公式,文章给出了R型环状纳米管TUC4C8(R)的Szeged指标的表达式。
對于一箇簡單連通無嚮圖G而言,其Szeged指標被定義為Sz(G)=∑e,這裏u, v∈V(G), e=uv, neu錶示圖G中到點u的距離小于到點v的距離的點數, nev的定義類似。S. Yousefi給齣瞭R型環狀納米管TUC4C8(R)的Wiener指標的計算公式,文章給齣瞭R型環狀納米管TUC4C8(R)的Szeged指標的錶達式。

For a simple connected undirected graph G ,the Szeged index of Gis defined asSz (G)=neun ev .neu counts the vertices of G lying closer to the uthan to v .The meaning of nev is analogous.S . Yousefi gave an exact expression for theWiener index of a TUC4C8(R)nanotorus.In this paper the Szeged index of a TUC4C8(R)nanotorus T =T[p ,q]is given.
