摘　　要：论文主要研究双论域粗糙集在心脏病诊断中的应用。首先,对心脏病患者的问卷调查数据进行相关性分析,得到心脏病类型与病症症状的二元关系。其次,利用双论域粗糙集的规则提取算法,分别获得由心脏病类型导出病症症状,以及由病症症状确定心脏病类型的规则。This paper mainly studies the application of rough set over dual-universes in the diagnosis of heart disease. First-ly,after analyzing the date got from questionnaire,the binary relations between the different types of heart disease and symptoms are established. In addition,two types of rules are obtained by using the extraction algorithm of the rough set over dual-universes：one is to use the different types of heart disease to deduce the corresponding symptoms,the other is converse.
