在Hindmarsh-Rose神经元动力系统中研究了Newman-Watts （NW）网络的同步，给出了一些最优同步网络的拓扑结构. 数值结果表明：NW网络的同步能力主要由耦合点在耦合空间的分布决定，耦合点分布均匀的NW网络一般具有较强的同步能力；在给定连边数的情况下，可能存在多个结构不同的最优同步网络，最优同步网络具有最强的同步能力、均匀的度分布和较好的对称性，但是其对称性不一定是最好的. 最优同步网络一般是非规则网络，但在少数情况下，规则网络也有可能是最优同步网络. 提出了一种新的网络——遍历网络，该网络具有最优同步网络的特点和很强的同步能力.

Synchronization in Newman-Watts (NW) networks is studied in a Hindmarsh-Rose neuron dynamical system. The topological structures of some optimal synchronization networks are given. Numerical simulation results show that the synchronizability of the NW network is mainly determined by the distribution of coupling points in coupling space. The network with even distribution of coupling points generally has the strongest synchronizability. For a given number of edges there may exist some optimal synchronization networks with different topological structures. Optimal synchronization network has the strongest synchronizability, homogeneous degree distribution and better symmetry. However, its symmetry is not necessarily best. In general, optimal synchronization network is an irregular network. However, in the minor cases, the regular network may be an optimal synchronization network. A new type of network, the ergodic network, is introduced in this paper, and it has strong synchronizability as well as the characteristics of the optimal synchronization network.-
