Hierarchical Model and Example about Research of Network Science

Currently,all kinds of complex network lie in the natural,physical,and social worlds,But we have little knowledge about hid common law of network. In order to make good use of network,we need to know more scientific things about network,named network science.The paper first analyses genesis,status, basic notion of network science and its influence on whole society,then discusses researchful hierarchical model of network science,including network structure layer for basic infrastructure,network modeling layer for formalization,network dynamic analysis layer for theoretical analysis and network function layer corresponding to different application,finally we give an example of network science model.
