RESUMO
This paper explored the methods of corpus linguistics application based on the corpus of doctor-pa-tient outpatient conversation, which was built by the project team members. Under the framework of the theory of conversation analysis, it discussed the inductive characteristics of subjective and functional repetition, and com-pared the similarities and differences of the repetition strategy use between patients and doctors. This study con-cludes a new OIR mode, enriching the theory of conversation analysis. The corresponding countermeasures of the repetition strategy use that put forward in this article provided a reference to strengthen the doctor-patient commu-nication, enhance the communication effect, and establish the interacted, cooperated and equal doctor-patient re-lationship. Meanwhile, it offered a new viewpoint to the study of doctor-patient communication.
