CHENG Jieqiong;School of Information Management,Central China Normal University;  
It has long been found that the citation network satisfies a certain distribution law,such as the continuity satisfies the power-law distribution,the node growth satisfies the exponential function and so on.Based on the statistics of patent literature,this paper studies the time mechanism of citation network:collecting the patents authorized by the United States in the past 40 years to construct citation network.Counting the growth of nodes in citation network,the distribution of the average number of references,the distribution of citation degree and other indicators in different periods.By analyzing the distribution of nodes,edges,citations and degrees of different patent documents,the variation law of these distribution parameters is analyzed.
