摘　　要：通过对广西师范大学门户网站的网页进行分层搜索,本文组建了一个以网页为节点、超链为边的有向网络,发现它的出入度分布均呈现良好的幂律分布特性,出度分布在开始部分出现弯曲。根据这些特性,本文提出了一种含有增长,择优和重连机制的有向网络演化模型,模型的演化机制较好的反应了广西师范大学网的这些特性。By searching the college web-site of GuangXi Normal University, a BFS and layered algorithm is used to construct a directed network which web pages are treated as vertices and hyperlinks as directed edges in this paper. After doing statistical analysis to the network, some features have been found that the vertex in-degree and out-degree indicate power-law distribution, and there is a curve in the beginning of out--degree distribution, According to these features, the evolvement model with growing, preferential and rewired mechanism of this complex directed network has been proposed, The Evolution Mechanism reflects some characterstics of the GuangXi Normal University Network.
