摘　　要：本文运用主方程等方法给出随机和择优混合演化网络模型稳态度分布存在性的严格证明,并推导度分布的表达式,进而得知该混合演化网络为无标度网络.In this paper the existence of the steady- state degree distribution of stochastic and preferred hybrid evolving network model is showed by applying the master- equation approach,furthermore,the analytic formula of the degree distribution is derived,and it is concluded that the network is a scale- free network.

关 键 词：择优演化网络 度分布 无标度
