摘　　要：[目的/意义]针对学科交叉宏观研究不能刻画学科交叉主题,以及学科交叉微观研究仍处于主题挖掘研究阶段的现状,从内容层面解决主题学科交叉度计算问题,并构建学科交叉分类的量化标准。[方法 /过程]首先,采集学术论文并解析引文内容;利用术语集获取术语和术语主题。然后,统计引文内容中的主题术语重复率。接着,计算学科间的主题学科交叉度。最后,基于主题学科交叉度分布熵,进行分类并分析。[结果 /结论]研究结果表明:(1)六个学科难以与医学在实践应用知识层面进行学科交叉;医学的理论基础与六个学科有明显的学科知识交叉。(2)学科交叉存在三种类型分别为:界内交叉、工具型交叉和界外交叉。综上,通过引文内容中的术语可以有效地计算主题学科交叉度,定量地研究学科交叉类型。[ Purpose/significance ] This paper calculates the interdisciplinary degree at a topical level and establishes quantitative standards for the interdisciplinary classification in terms of the contents, because the current issues of interdisciplinary macro-research lack the description of interdisciplinary topics, and interdisciplinary micro-research is still in the topic detection stage. [ Method/process] Firstly, full-text articles were collected, and terminologies were extracted. Secondly, the repetition rate of subject terminologies in citation contents were calculated. Then, the degrees of topical interdisciplinarity were calculated. Finally, the disciplines were categorized according to the topical distribution entropy of interdisciplinarity. [ Result/conclusion] The results are as follows： （i） All six disciplines share abundant interdisciplinary knowledge with much medical theoretical basis knowledge but rare medical practical knowledge. （ii） Three types of interdiscipline are observed： internal interdiscipline, instrumental interdiscipline, external interdiscipline. In conclusion, the interdisciplinary types can be quantitatively studied at the micro level through the terminologies in the citation content.
