摘要
应用网络科学的理论方法,基于实际数据,提出优先权排队网络模型,建立全球核电站网络;利用数值模拟研究了网络拓扑特性(度分布和群聚系数等);利用CFinder软件研究了网络的社团结构。结果揭示了全球核电站网络分布具有不平衡性和不均匀性,并基本反映了发达国家(节点度大)广泛采用成熟堆型、发展中国家(节点度小)从发达国家引进的事实。全球核电站网络相关的各种特性可反映全球核电站的发展现状及其核电站网络的演化特点。这些结果从网络科学视角为我国核电站的发展提供依据和参考。
Based on the realistic data,the priority queue network model was proposed and a global nuclear plant network（GNPN）was constructed by means of the theories of network science.The topological properties of the network such as the degree distribution and the clustering coefficients were numerically simulated,and the community structure of the network was discussed by a software named CFinder.The results reveal that the distribution of GNPN is of hyperdispersion and nonequilibrium distrinution. From the structure of the network,we can also deduce the fact that the common reactor types are widely used in developed countries（node degree is large）.However,developing countries（node degree is small）purchase them from the developed countries.All characteristics of GNPN can reflect the status and evolution of nuclear plants in different countries and they may be valuable for the concerned research in China.
