摘　　要：世界上大部分的复杂网络都具有无尺度特性,可称之为无尺度网络。无尺度网络中集散节点的脆弱性已经引起了各领域的重视,在前人研究成果的基础上,采用一种集散节点的控制策略——环网等效。与原无尺度生成网络相比,集散节点的聚集度得到了缓解,集散节点的脆弱性也降低了,从而提高了网络结构的可靠性。The most complex network in the world can be called scale-free network has scale-free characteristic.Vulnerability of hubs in scale-free networks has aroused the attention in each field,on the basis of the previous studies,this paper puts forward a control strategy of hubs：Ring equivalent.Compared to the original scale-free network,the hubs get ease,the vulnerability of hubs has been brought down,so as to enhance the reliability of the network structure.

关 键 词：无尺度特性 集散节点 环网等效 分布式
