| Abstract: | Firstly the paper gives the studing results for evaluating model of information source in citation system. Then based on the complex citation system expressed by a weight digraph in citation system, it disscusses the theory of several evaluating modles in citation system and refers that the simple statistic model is the resembling model. Base on the condition of primitive connectivity,it lastly defines the existence theorem and uniqueness theorem and be independent of initial,and explains with example and diagram. |
