Abstract:  Based on the study of the type, characteristics and examination method of local patterns of mastoid lines, this paper analyzed the application of local morphological characteristics of mastoid lines in fingerprint examination cases. It is demonstrated that the presented characteristics were operational, and could enhance the utilization of incomplete, less features and other difficult fingerprints. The local characteristics of mastoid lines are important supplements to regular fingerprint characteristics, which have practical significance in the fingerprint examination.

Key words:  fingerprint examination, local morphologies of mastoid lines, characteristics

摘要：   在手印检验工作中，通过对乳突纹线局部形态特征的种类、特点及检验方法进行研究，并运用实际案例进行分析阐述，论证该类特征在手印检验中具有可操作性，能够提高残缺、少特征等疑难手印的利用率。乳突纹线局部形态特征的应用是对常规特征的重要补充，对手印检验工作具有实际意义。
