Abstract


The network is increasingly becoming the academic study of the scientists , an important platform for research cooperation, information exchange , research academic information distribution network structural units phenomenon and law , to make people more efficient organization of network resources , help to establish more effective search methods , in order to effectively grasp the effective management and control of the network information flow . In this paper, Scirus science search engine on the H5N1 avian influenza network of academic information distribution , and analysis of the distribution of academic information in electronic journals and website are two different grid cells , and reached the following conclusions : 1 . Similar to Brad Telford 's law , network cases , the distribution of academic information resources still reflects the centralization and decentralization law - most are concentrated in a small number of electronic journals or websites on distribution to meet twenty-eight law . Compared to the distribution law but under the conditions of this distribution law and traditional journal publishing and new . 2. Academic information distributed in different types of network element , the respective characteristics of different network type own characteristics exhibited by the concentrated dispersion law , and does not fully meet the classical laws of 1 : A : of a ~~ 2 : ...... proportional relationship. Website academic information distribution reflected more dispersed , less concentration information . 3 . Brooks regression analysis of mathematical expressions and standard formulas , both in form is exactly the same , and precision than Lyme Kule function . 4 . Use the Bradford area method and image method two methods , consistent H5N1 avian influenza academic information core electronic journals and core website . Visible network case , Bradford area method and image method is an important method to determine the core journals and core sites .
