图的匹配总数被定义为它的Hosoya指标。刻画了具有最大Hosoya指数和短径的共轭和非共轭无圈图，并给出了这些极图的Hosoya指数的显式表达式。
The total number of matchings of a graph is defined as its Hosoya index. Conjugated and non-conjugated acyclic graphs that have maximal Hosoya index and short diameter are characterized in this paper, explicit expressions of the Hosoya indices of these extremal graphs are also presented.
