        Relation Fusion,a new research trend in research field analysis,is an approach to mapping the structure of research fields by combining different relationships of same type entity.Fisher-based Multiple Relations Fusion Method(Fisher-based MRFM) is a typical method of Integration Method,but the result of analysis of its procedure indicates that Fisher-based multiple relations fusion is impaired to extreme value.Base on these researches,z-score Based Multiple Relations Fusion Method(z-score Based MRFM) is proposed,which not only solves the problem mentioned above,but also simplifies the calculation procedure.The experiment result verifies the advantage of z-score Based MRFM over Fisher-based MRFM.
