【摘要】：中國是世界上稀土儲量最多的國家,稀土產(chǎn)業(yè)是我國的特色產(chǎn)業(yè)。為了解稀土研究的前沿和趨勢,本文通過知識計量學(xué)方法,以Web of Science數(shù)據(jù)庫中1985~2015年發(fā)表的學(xué)術(shù)論文中的作者關(guān)鍵詞為知識單元,利用知識圖譜分析軟件Sci~2工具包對稀土研究領(lǐng)域進行知識計量分析。首先,通過關(guān)鍵詞共現(xiàn)分析探測稀土研究領(lǐng)域的前沿;其次,通過突現(xiàn)檢測分析稀土研究領(lǐng)域的趨勢;并結(jié)合中國稀土研究的特點,對稀土研究前沿和趨勢進行綜述。結(jié)果表明,中國的發(fā)文量在國家/地區(qū)中居于首位,中國科學(xué)院在相關(guān)機構(gòu)中發(fā)文量最多;稀土研究前沿的主題主要有稀土合金和化合物、發(fā)光、X射線衍射、磁性、中子衍射、磁性測量以及光致發(fā)光等方面;稀土研究趨勢的主要突現(xiàn)關(guān)鍵詞有稀土化合物、熒光粉等。
[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.
