Then by means of maximum matching number we give aformula to calculate the nullity of unicyclic graphs.

第三章主要给出计算单圈图的零度的公式。

In this paper, inverse degree of unicyclic graphs and bicyclic graphs is discussed, and the extremal graphs that reach the upper and lower bounds are given.

研究了单圈图、双圈图的反比度，给出了它们的上下界并得到达到最大最小值的极图，还进一步给出多圈图的上下界的一个猜想。

The order of unicyclic graphs according to their largest eigenvalues is studied in this paper, and the first six unicyclic graphs in this order are determined.

主要讨论了单圈图按其最大特征值进行排序的问题，确定了该序的前六个图。
