摘要：
The modified Schultz index of a graph G is defined as S* (G) = Sigma({u,) (v}subset of V(G)) (d(u) . d(v))d(G) (u, v) where d(u) (or d(v)) is the degree of the vertex u (or v), and d(G)(u, v) is the distance between u and v. Explicit formulas for calculating the modified Schultz index of nanotubes covered by C-4 are provided in this report.
