摘　　要：就EI叙词表与我国47部叙词表的微观结构进行对比,提出从概念深度、概念分化度、概念聚合度、概念横向关联度四个方面来描述和评价词表纵深结构和横向关联结构的方法。通过分析,发现EI叙词表概念体系纵深大、分化度高、聚合度高、横向关联点多、入口率高,在结构上更合理。据此对比分析结果,指出我国叙词表在微观结构上存在的问题以及在新的技术环境下编制叙词表的建议。There are hierarchical relations, associative relations and preferential relations in thesaurus. This paper contrasts these relations in EI Thesaurus and 47 Chinese thesauri. Four measures are proposed and used in the analysis of thesaurus microstructure, including concept depth measure, concept differentiation measure, concept convergence measure and concept cross - connection measure. The comparative analysis indicates that EI Thesaurus has more suitable microstructure to new technology environment. Based on the EI Thesaurus feature, the paper gives some proposal on Chinese thesauri establishment.
