A new network routing algorithm is proposed, which follows calculation rues of logic algebra and calculates routes with depression of order transformation of incidence martrix. For network with m nodes, m-2 times depression of order transformation operations can get all routes between two nodes. Furthermore, it accords with the communication transmission rules and avoids the close loop routes.

提出一种网络路由新算法，是按照逻辑代数运算规则，以关联矩阵降阶变换方式计算，对于有m个节点的网络，只需m-2次距阵降阶变换运算，就能够算得网络两节点间全部路由，且不会出现闭环路由问题，完全符合通信传输规则。

In particular, when thereis an alternating group A_5 action on a Spin 4-manifold X, we obtain: If X is smooth Spin4-manifold with non-positive signature and b_1=0, denote k=-σ/16 and m=b_2~+,then 2k+3≤m if b_2~++b_2~+≠2b_2~+(Z/A_5) and b_2~+≠0,where and are subgroups of A_5 generated by the elements s=∈A_5and t=∈A_5 respectively.

特别地，在Spin 4-流形具有非交换群A_5作用时，我们得到了：若X为光滑的具有非正符号差的Spin 4-流形，b_1=0，令k=-σ／16，m=b_2~+，如果X上具有Spin交错群A_5作用，且满足b_2~++b_2~+≠2b_2~+(X／A_5)，b_2~+≠0，则2k+3≤m，其中和分别为s=∈A_5和t=∈A_5生成的A_5的子群。

The results are as follows: 1The collagenous fibers are arranged in a crass-crossed network of three dimentions. The network in an area of less than 500 μm is like a small board called a microboard. All microboards anastomose each other, forming a microboard network; 2The so-callcd collagenous fibers or lamellae about 4—9 μm thick under the LM are really th...
