基于CNKI数据库的陶瓷膜文献计量及可视化分析

Bibliometric and visual analysis of ceramic membrane based on CNKI

陶瓷膜作为一类典型的化工新材料,是石油化工等过程工业的理想分离材料之一.本文基于中国知网数据库对陶瓷膜材料相关的文献进行检索与梳理,从检全率和检准率两个维度评价了检索策略,并对文献的时间分布、期刊分布和学科分布进行了分析.借助Citespace和VOSviewer两款软件,通过作者共现图谱和关键词聚类图等对文献进行了可视化分析.结果显示,陶瓷膜的研究呈现显著的化工学科属性,刊文量占所有学科类别的53%.目前,陶瓷膜研究领域的核心作者群体已经初步形成.陶瓷膜应用存在“长尾效应”,但这些频次低、数量多的应用场景中潜在着众多研究热点和行业新增长点.

As a typical new chemical material,the ceramic membrane has been one of the ideal separation materials for petrochemical and other process industries.Here,we carried out literature retrieval and collection for the research of ceramic membranes based on the CNKI database.The retrieval strategy was quantitatively evaluated from two dimensions of inspection rate and accuracy.The distributions of publication time,journal,and related subjects were systematically analyzed.With the help of two software,Citespace and VOSviewer,the literature was visually analyzed through the co-occurrence map of authors and the cluster network of keywords.The results show that the subject of ceramic membrane research is significantly attributed to chemical engineering,of which the publication ratio is as high as 53%.The core author group has initially formed in the field of ceramic membrane research.There is a“long tail effect”in the application of ceramic membranes.However,these low-frequency and high-volume applications have great potential for scientific research and industry development in the future.
