| 摘 要： | 现实世界许多复杂系统描述为复杂网络拓扑后，节点连通度呈幂律衰退，网络中存在少量的高连通度节点和大量的低连通度节点，本文研究了复杂网络的网络拓扑熵与网络结构的关系，从系统的开放性、远离平衡态、非线性相互作用以及随机涨落的角度对网络进行了分析，认为复杂网络拓扑结构是系统自组织演化的结果．

| Abstract: | When a number of complex systems in real world are described by complex network topology,their vertex connectivity follows powerlaw distribution,having only a few of highconnectivity vertices,but a great deal of lowconnectivity vertices in network.In the paper,the relationships between complex networks' topologic entropies and their structures are studied.From view points of system opening,nonequilibrium state,nonlinearity interaction and stochastic fluctuation,complex network's topologic structures are discussed.It is concluded that this is due to the result of systems' selforganization evolution process. |
