| Abstract: | The distribution of power law is an important characteristic in scale-free network.Based on theory of non-linear BA model,we give the algorithm of graph G*(m,N,β),and research the model under three forms of β,which are 0< β<1,β>1and β→+∞.Under dissimilarity of β,different power law distributions of Pr are obtained. |

| Keywords: | scale-free networks power exponent BA model non-linear |
