| 摘 要： | 本文提出了一个非线性扩张的复杂网络模型，在这个模型中，同时考虑了节点和边的非线性增长。结果表明，网络的度分布呈现双幂律分布，幂指数分别为γ1〈2和γ=3，双幂律分布的转折点受到节点后κcross和边数的增长率的控制。

| Abstract: | We present and investigate a general nonlinear growth network model which incorporates accelerated growth of nodes and edges. This model predicts an observable two. regime scale free degree distribution, where the sealing exponent are γ 〈2 and γ≈3 respectively. The crossover point kcross of the degree distribution is adjusted by the growth rates of nodes and edges. |
