| 通过文献计量方法对分子机器的发展脉络和研究趋势进行分析，发现国家、机构、科研人员
的合作情况及热点的变化。使用科学知识图谱软件 CiteSpace 对 1959 年—2019 年7月25日、检索自
Web of Science 核心合集数据库中的文献进行分析，挖掘分子机器领域的国家、机构、科研人员的合作
情况，并通过关键词聚类分析发现研究热点及发展趋势。美、英、法、意、荷、日是当前全球分子机器领
域研究实力较强的国家，中国发文量较大但影响力稍弱；机构间的合作主要集中在美国和欧洲之间，中
国与日本、美欧之间的合作较少；以斯图达特为代表的欧美国家研究人员具有较大的国际影响力，相比
之下，中国研究人员在国际上的影响力较低；分子机器目前正在从设计合成、控制复杂结构分子运动向
新材料和新功能器件的突破方向发展。 |
| 英文摘要: |
| This paper uses bibliometrics’ method to analyze the development and the research tendency of
molecular machines, and to find countries, institutions, researchers and the change of the research hotspots. This
paper analyses articles between 1959 and 25.7.2019 which from Web of Science by CiteSpace, a mapping software
of scientific knowledge, to explore the cooperation among countries, institutions and scientific researchers in the
field of molecular machine. Hot topics and development trends through keyword clustering analysis are discussed
too. The United States, Britain, France, Italy, Netherlands and Japan are the countries with strong influence in the
field of molecular machine. Cooperation between institutions is mainly between the United States and Europe,
while cooperation between China and Japan, China and the United States, China and Europe are less. The
European and American researchers represented by Stoddart have great influence in the whole world. Research
topics in the field of molecular machine are gradually turning from designing, synthesizing and controlling the
movement of complex structural molecules to exploring new functionally materials and devices. |
