We applied a mean-field approach to study clustering coefficients in Barabási-Albert (BA) networks. We found that the local clustering in BA networks depends on the node degree. Analytic results have been compared to extensive numerical simulations finding a very good agreement for nodes with low degrees. Clustering coefficient of a whole network calculated from our approach perfectly fits numerical data.
我们应用平均场方法来研究巴拉巴西-阿尔伯特（BA）网络中的聚类系数。我们发现BA网络中的局部聚类取决于节点度。已将解析结果与大量数值模拟进行比较，结果表明对于低度节点两者吻合得非常好。通过我们的方法计算得到的整个网络的聚类系数与数值数据完美拟合。
