通过科学计量学方法,以Web of Science数据库1985—2015年发表的学术论文为基础,利用知识图谱分析软件VOSviewer和Sci2工具包对稀土研究领域进行可视化分析。首先通过文献共被引分析稀土研究的知识基础,其次通过关键词共现分析探测稀土研究领域的研究前沿,最后通过突现检测分析稀土研究领域的研究趋势。研究结果表明:中国的发文量在国家/地区中居于首位,中国科学院在相关机构中发文量最多;稀土研究知识基础的重要文献形成3个聚类;稀土研究前沿的主题主要形成稀土发光材料、稀土永磁材料、稀土储氢材料、稀土化合物和化学合成法5个聚类;稀土研究趋势主要的突现关键词包括稀土化合物、荧光粉等。
Based on the scientific papers published in the Web of Science database from 1985 to 2015, the field of rare earth research was visualized with the help of the knowledge mapping software VOSviewer and Sci2 toolkit. First of all, through the literature co-cited analysis of the knowledge base of rare earth research, followed by co-occurrence of key words to explore the research frontiers of rare earth research, and finally through the sudden detection of rare earth research and analysis of research trends. The results show that: the number of papers published in China ranks first in the country / region, and the Chinese Academy of Sciences has the largest number of papers published in related institutions; three clusters of important documents on the basis of knowledge of rare earths research; the leading topics of rare earth research mainly form rare earth luminescent materials, Rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth compounds and chemical synthesis of five clusters; rare earth research trends include: rare earth compounds, phosphors and so on.
