摘要：
We derive the expressions of the ordinary, the vertex-weighted and the doubly vertex-weighted Wiener polynomials of a type of thorn graph, for which the number of pendant edges attached to any vertex of the underlying parent graph is a linear function of its degree. We also define variable vertex-weighted Wiener polynomials and calculate them for the same type of thorn graphs. Copyright (C) 2009 John Wiley & Sons, Ltd.
