指纹乳突纹线密度的性别差异初探

Sex differences from fingerprint ridge density in the Chinese Han Population

目的针对指纹纹线密度在不同性别间是否存在差异进行了研究和探索。方法实验对80个(其中男女各40人)中国汉族人十指纹线密度进行计数,将所得数据通过SPSS软件进行统计分析。结果指纹纹线密度均值男性少于14.5线/25mm2,女性大于等于15线/25mm2。结论男女之间指纹密度存在差异;女性指纹纹线密度较男性高。

Objective To study the gender differences in fingerprint ridge density in the Chinese Han population.Methods Fingerprint ridge density of 40 male individuals and 40 female individuals of Chinese Han population were counted and analyzed by SPSS software.Results The mean ridge density of fingerprints of 40 male individuals was less than 14.5 ridges/25mm2 and the mean ridge density of fingerprints of 40 female individuals was more than 15 ridges/25mm2.Conclusion The significant gender differences occur in the finger ridge density.
