This paper,by means of a new method,the graph theory,reanalyses the stability of antisymmetric discrete Hopfield networks,avoiding the construction of energy function.The nessesary and sufficient conditions for a network to converge to a cycle of length 4 are presented,and the number of cycles of length 4 associated with a p-order antisymmetric discrete Hopfield network is discussed,with some suspicions presented.

本文应用一种新的方法——图论方法重新系统地研究了反对称离散Hopfield网络的稳定性理论，这种方法回避了构造能量函数的麻烦，本文给出了网络收敛于长度为4的环吸引子的充分及必要条件，讨论了p阶反对称离散Hopfield网络含有长度为4的环吸引子的数目，并提出了几个尚待解决的猜想。

In a child the outer annular fibres attach to the edge of the cartilage plate; in an adolescent they attach to the ring apophysis; and in an adult they attach to the outer vertebral ring.

孩童时期，外围环状纤维附著在软骨板的边缘；青少年时期，附著在骨突环；成人时期，附著在外围椎骨环。

The ADDPS means that to find,if possible,a controllerunder which the influence from the disturbance to the output of closed loop systemcan be reduced to arbitrarily small and the closed loop system is of internal stability.

ADDPS就是对一个有外部干扰输入影响的系统，寻求一个反馈控制律，使得干扰输入对闭环系统输出的影响可以充分小，并且保持闭环系统是内部稳定的。

Byproperly choosing arbitrary parameter,not only the pole assignment of close-loop system can be done arbilrarily but also its other performance demands can be satisfied.obtained.

通过对任意参数的适当选择，不但能使闭环系统的极点任意配置，还可满足闭环系统的其他性能要求。

Considered the inside and outside contour line was Archimedes spiral in the cold rolling, the forming law of rectangular cross sectional rings has been studied. And the more precise geometrical models and calculation models have been gained. The researches can be used as a theoretical and experimental foundation for the simulation of ring rolling process. At the same time, the results of theoretical analysis have a good agreement with the results of practical rolling production.

本文在考虑冷轧过程中环件的内外轮廓线均为阿基米德螺线的情况下，对矩形截面环件的轧制成形规律进行了研究，得到了较精确的几何模型和计算模型，为环件轧制过程的模拟提供了理论依据和实验依据，同时理论分析的结果与实际轧制生产过程中的结果有较好的吻合。
