中文摘要：

研究了具有固定节点与连接数的非增长Bianconi-Barabasi（B-B）模型的临界现象.解析的分析表明这一模型展现了一个凝聚-非凝聚相变.数值模拟了这一模型在玻尔兹曼极限下的临界行为,发现它的非凝聚相和B-B模型的非凝聚相（FGR相）有着显著的不同,也确定了相应的临界温度和连接度分布.

英文摘要：

The critical phenomenon of the non-growing Bianconi-Barabasi（B-B） fitness model with fixed number of nodes and links was analyzed.The analytical studies show that this model displays a condensate-non-condensate phase transition.The critical behavior was numerically simulated in the Boltzmann limit,suggest that the non-condensation phase is significantly different from that of the growing B-B model.The corresponding critical temperature Tc and degree distribution P（k） are identified.
