【摘要】：中国是世界上稀土储量最多的国家,稀土产业是我国的特色产业。为了解稀土研究的前沿和趋势,本文通过知识计量学方法,以Web of Science数据库中1985~2015年发表的学术论文中的作者关键词为知识单元,利用知识图谱分析软件Sci~2工具包对稀土研究领域进行知识计量分析。首先,通过关键词共现分析探测稀土研究领域的前沿;其次,通过突现检测分析稀土研究领域的趋势;并结合中国稀土研究的特点,对稀土研究前沿和趋势进行综述。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;稀土研究前沿的主题主要有稀土合金和化合物、发光、X射线衍射、磁性、中子衍射、磁性测量以及光致发光等方面;稀土研究趋势的主要突现关键词有稀土化合物、荧光粉等。
[Abstract]:China has the most rare earth reserves in the world, and rare earth industry is the characteristic industry of our country. In order to understand the frontier and trend of rare earth research, the authors' keywords in the academic papers published in Web of Science database from 1985 to 2015 are taken as the knowledge unit through the method of knowledge metrology. The knowledge quantitative analysis in rare earth research field was carried out by using the knowledge map analysis software Sci~2 toolkit. Firstly, the research frontier of rare earth is analyzed by cooccurrence analysis of keywords; secondly, the trend of rare earth research is analyzed by emergent detection; and combining with the characteristics of rare earth research in China, the research frontier and trend of rare earth are summarized. The results show that the number of papers published in China is the first in the country / region, and the Chinese Academy of Sciences has the largest amount of papers in the relevant institutions. The main topics in the research frontier of rare earths are rare earth alloys and compounds, luminescent X-ray diffraction, magnetism, neutron diffraction, etc. Magnetic measurement and photoluminescence, the main keywords of rare earth research trends are rare earth compounds, phosphors and so on.
