摘要
近红外光谱作为一种无损、高效、便捷的检测技术,具有操作简单、分析成本低、结果重现性强等优点,是一个具有较强综合性的跨学科研究领域.基于文献计量对CNKI收录的近红外光谱领域1979～2021年的14207篇中文文献,以及WOS核心合集收录的该领域1993～2021年的37244篇外文文献从年度发文趋势、发文机构、资助基金、关键词共现、国际合作情况、热点前沿等角度进行可视化分析.结果表明,近年来,近红外光谱领域的研究在全球范围内总体上呈现出趋冷的态势,相较于一些国家,尽管我国在该领域的研究水平较为成熟,但其研究方向及覆盖领域较为单一.
Abstract
As a nondestructive,efficient and convenient detection technique,near infrared spectroscopy has the ad-vanta-ges of simple operation,low analysis cost and strong reproducibility of results,which is a highly comprehen-sive and inter-disciplinary research field.Based on bibliometrics,14207 Chinese literatures from 1979～2021 inc-luded in CNKI and 37244 foreign literatures from 1993～2021 included in Web of science Core Collection in the field of near infrared spectros-copy were visually analyzed in terms of annual publication trends,publication instit-utions,fund,co-occurrence of key-words,international cooperation,hotspot and frontier,etc.The results show that in recent years,the research of near infra-red spectroscopy worldwide has generally shown a trend of cooling.Com-pared with some countries,China's research in this field is relatively simple in direction and coverage,though reac-hing a relatively mature level of research.
