Abstract ：
This paper deals with the structure of essentially disconnected benzenoid systems. The normal components induced digraph is introduced. It is proved that for an essentially disconnected benzenoid system, its normal components induced digraph is acyclic and connected. The lower bond for the number of normal components of an essentially disconnected benzenoid system is investigated. Moreover, the essentially disconnected benzenoid systems with two or three normal components are classified and constructed.

Abstract ：
A maximum matching of a graph G is an edge set with the most independent edges of G. A fixed single (double) bond of G is an edge belongs to no (each) maximum matching of G; a fixed bond is either a fixed single bond or a fixed double bond. Let G be a polyhex with bipartition (W, B) satisfying vertical bar W vertical bar = vertical bar B vertical bar. In this paper, we give sufficient and necessary conditions which enable us to determine the size of a maximum matching of G and to recognize the fixed bonds of G.

Abstract ：
A generalized polyomino graph is regular if it can be subjected to a series of special cell-shedding transformations, square by square, down to a single square. In this paper, we give a necessary and sufficient condition to determine whether or not a generalized polyomino graph is regular.

Abstract ：
A special type of covering of polyhexes introduced by Gutman [1] is investigated. It is proved that for a primitive coronoid system the number of covers is equal to the number of Kekule structures minus three.

Abstract ：
An essentially disconnected coronoid system is defined as a Kekuléan coronoid system which has fixed (single or double) bonds and has at least one hole. It is proved that the subgraph, obtained by deleting all the fixed single bonds and all the end vertices of the fixed double bonds, is disconnected, and has at least two normal components, which generalizes the result for essentially disconnected benzenoid systems by Gutman et al [4].
