| 摘 要： | 为了更深入理解DDC与UDC的差异，设计出更优质的知识组织系统（Knowledge Organization System），文章采用领域专家分析和量化对比方法，对最新版本的DDC和UDC工程相关范畴类目进行对比分析。分析结果表明：①DDC与UDC的知识面覆盖重合度较高；② DDC范畴类目划分整体上较UDC更为细致；③DDC与UDC范畴类目设置存在较大差异；④DDC与UDC的差异主要是由两者知识描述角度的差异造成的。

| Abstract: | For a more in-depth understanding of the difference between DDC and UDC to design a bet er knowledge organization system, the latest version of the DDC and UDC Engineering disciplines-related categories were analyzed by the authors using the domain expert analysis and quantitative comparison method. The results show that：①the knowledge coverage of DDC and UDC is high;②DDC categories are divided more minutely than UDC;③the category set ing is quite different between DDC and UDC;④the differences between the DDC and UDC categories are mainly caused by the angle of knowledge describing. |
