摘　　要：网络环境下的《汉语主题词表》(工程技术版)不再是传统的叙词构建概念,它可以根据论文关键词的词频或用户使用的自由词来检索,其等同关系中非叙词的比例大为增加。新版本的编制应注重等同关系的建立及同义词群的构建、等级关系的建立及概念指引聚集语义大小的辨析,并充分考虑用户检索用词和文献主题的准确表达,实现叙词表词库与用户检索用词最大限度的一致,从而能为更多的人员使用。The Chinese Thesaurus （Engineer and Technology Edition） in the context of network environment is no longer the traditional one; the frequency of key words and the free terms defined by users could be employed to retrieve the thesaurus, therefore, the proportion of non-descriptors with the equivalence relationship is on the increase. To compile the new Chinese Thesaurus, attention should be paid to several aspects, such as, the construction of equivalence relationship and synonyms; building the hierarchical relationship, distinguishing the aggregating degree of semantic by concept, taking full account of the correct expressions of search words for users and document subjects, thus making the lexicon best meet up with users＇ search words and letting the Chinese Thesaurus be used more widely.
