[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.
