本文通过文献计量学相关方法,对PubMed数据库2001～2011年收录的航天医学类非综述文献进行分布研究,统计分析了论文的年度分布、核心期刊分布、核心作者分布、语种分布、国别分布等;同时,对出现次数超过一定阈值、能准确表达文献内容的MeSh主题词进行共现聚类分析,结合语义分析,以发现航天医学领域近10年的主要研究热点。分析结果对于科研人员检索文献、了解关注领域研究状况,以及科技期刊编辑的选题策划方面均有借鉴和参考意义。
In this paper, by means of bibliometrics, we study the distribution of non-review articles of aerospace medicine published in PubMed database from 2001 to 2011, and analyze the annual distribution, core periodical distribution, core author distribution, linguistic distribution, country distribution and so on At the same time, co-occurrence clustering analysis was carried out on MeSh keywords that appeared more than a certain threshold and could accurately express the content of the documents. Combined with semantic analysis, the main research hot spots in the field of space medicine were discovered in the past 10 years. The results of the analysis have a reference and reference value for researchers to search the literature, understand the research situation in the field of interest, and select the topics for the editors of sci-tech periodicals.
