摘　　要：探讨了PubMed,EMBASE.COM,Web of Science,中国知网,万方和维普6个文献数据库相关文献功能及其实现机制,对比分析了国内外文献数据库在相关文献提供方面的特点。结果显示,国外文献数据库检索系统的相关文献功能比较单一,具有较强的针对性和实用性;而国内文献数据库的相关检索功能相对比较完善,不仅能提供基于外部特征的相关文献,还能提供相关(关键词或分类号)文献的简单内容。在相关文献的实用性方面,中国知网优于万方数据库,万方数据库优于维普数据库。The related article functions in PubMed,EMBASE. COM, Web of science,CNKI, Wanfang and Weipu and their implementation mechanisms were studied. The features of related articles provided by these data- bases were compared and analyzed, showing that the retrieval system-related article functions in foreign databases are relatively simple, targetable and practical, while those in domestic databases are relatively perfective, which can thus provide not only the outside features but also the simple contents of related articles, and that the practicality of related articles is better in CNKI than in Wanfang, and in Wangfang than in Weipu.
