以JCR数据库中期刊间的引用关系为基础,应用期刊引文网络分析方法,从学科整体和期刊个体两个层面分析纳米科技学科领域的知识交流。在学科整体层面,发现纳米科技内部知识交流密集,NANOTECHNOLOGY、NANO LETT和J PHYS CHEM C等期刊是知识交流的核心节点。在期刊个体层面,通过分析NAT NANO和NANOMED这两种代表性期刊的引证网络和被引网络,发现纳米科技在学科间的知识交流中起纽带作用。
Based on the citation relationship between journals in JCR database, this paper analyzes the knowledge exchange in the field of nanoscience and technology from two aspects: the whole subject and the individual journals by using the journal citation network analysis method. On the whole subject level, knowledge exchange within nanotechnology is found intensively. Journals such as NANOTECHNOLOGY, NANO LETT and J PHYS CHEM C are the core nodes of knowledge exchange. At the individual level of journals, by analyzing citation networks and citation networks of two representative journals, such as NAT NANO and NANOMED, nanotechnology has been found to play a role as a link in knowledge exchange among disciplines.
