摘要：
Three graph-transformations are introduced for maximizing the total number of matchings of a graph, by which chemical trees that have maximal energy and any prescribed maximum vertex-degree are characterized. Orderings of n-vertex chemical trees are presented according to their energy, some of which contain approximate n trees. Finally, acyclic graphs with maximal energy but without perfect matchings are also characterized.
