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。

Firstly, full factorial experiment method is implemented to achieve an optimization of longitudinal microstructure design in the incidence plane of a LGP for LED BLUs. There are three control factors involving in the optimization process: the pitch and depth of both V-cut and U-cut, and angle and radius for V-cut and U-cut, respectively. Each individual control factor has three levels. It leads to a total of 27 sets of experiments.

本实验先行讨论全因子实验求取发光二极体背光模组之导光板入光侧纵沟微结构最佳化设计，选定入光侧V-cut纵沟微结构控制因子：V-cut角、V-cut间距、V-cut深及入光侧U-cut纵沟微结构控制因子：U-cut半径、U-cut间距、U-cut深等项目，其中各一因子分别有三个水准变化，依控制因子及其水准的目各进行27组实验。

Preparation: garlic, dry and fresh chilis, onions (red onions smell great, white/normal onions taste sweet, we need both, blend them with blender also), Cymbopogon (the middle part cut it finely, smell better; outer part just cut to long piece, fine cut will be bitter), Galangal, chicken cut to pieces (marinate with sugar, salt, a bit soya sauce, not too wet), slice Turmeric leaf (we can't find this leaf in germany, so we use lemon leaf to substitute)...

准备材料：蒜米，辣椒干和新鲜辣椒，洋葱（红洋葱香，白洋葱甜，两个都要，用搅拌机打碎），香茅（中间嫩芯切碎，比较香；外面的切大段，切碎会苦），南疆，鸡肉切块（用糖盐，少少酱油腌，不要太湿），黄姜叶切丝（我们这里没有这个daun kunyit，就拿柠檬叶代替）。。。
