In this paper, firstly, not only the incidence matrix ,adjacent matrix, cycle matrix, cut-set matrix of an undirected graph are summarized, but also the close contact between a graph and its corresponding matrix are discussed ; secondly, many problems of a graph which are solved by analysing its matrix are listed as follows:1、The co-tree set of a graph is obtained by using its cycle-matrix ; 2、The branches of its spanning tree are given by using its cut-set matrix ; 3、By making use of the incidence matrix of a graph ,not only its vertex cut 、cut vertex 、isolated point and spanning tree can be obtained ,but also the two sides which are whether parallel or not can be judged ;4、By using their adjacent matrix ,the two graphes which are whether isomorphous or not can be judged; once more, there is a detailed introduction in view of special graph (for example: bigaritite graph ,regular graph and so on);last but not least, a graph method of calculating the N power of a matrix is given and the practical applications of the theorem for degree is indicated.

本文首先综述了无向图的关联矩阵,邻接矩阵,圈矩阵,割集矩阵以及图和它对应矩阵之间的关系;其次总结出了利用上述各类矩阵可以解决的图的若干问题:1、利用图的圈矩阵可以求其连枝集;2、利用图的割集矩阵可以求其生成树的树枝;3、利用图的关联矩阵不仅可以求其割点、点割集、连通度、孤立点和生成树,而且可以判断两条边是否平行;4、利用图的邻接矩阵可以判断两个图是否同构;再次,针对特殊图(例如:二分图、正则图等等)的邻接矩阵作了详细介绍;最后,得到了利用图计算矩阵的N次幂的方法,指出度数定理的实际应用。

布卢姆暗自同意斯蒂芬的论点。布卢姆认为斯蒂芬之所以晕倒乃是因为他胃囊里空空如也,以及搀水量与酒精度数各不相同的化合物在作怪。这是始而精神紧张,继而又在松弛的气氛下疾迅地旋转这一剧烈的运动所造成的。斯蒂芬却把它归因于起初还没有女人的巴掌那么大的晨云再次出现(他们二人曾从不同的地点--沙丘与都柏林,目击到那片云彩)。
