河北汉族青少年指纹纹型的分析

目的:通过指纹纹型分布,为人类学和临床医学提供基础皮纹学参数.方法:无油墨法采集400例河北汉族青少年的指纹,放大镜下鉴定.结果:斗形纹占49.425%,箕形纹占48.300%,弓形纹占2.275%.弓形纹多见于食指,其次是拇指;箕形纹多见于小指,其次是中指;斗形纹多见于环指,其次是拇指.双手十指同纹型的频率为16%.一手五指纹型组合频率为OLW (65%)>同型组合(26.125%)>ALO(4.5%)>ALW(4.375%).对应手指纹型组合频率为:W/W(40.95%)>L/L(38.75%)>L/W(16.65%)>A/L(2.5)>A/A(0.9%)>A/W(0.25%).结论:对应手指同型组合频率为80.6%,指纹纹型分布具有对称型.

Analysis of fingerprint patterns of Han adolescences in Hebei

Obiective: To study distribution of fingerprint patterns of 400 Han adolescences in Hebei, and provide normal parameters for genetics, medicine and anthropology. Methods: Fingerprint was obtained using ink method and identified by magnifier. Results: The normal values of the fingerprint patterns on the Han nationality of Hebei were reported. There were 400 persons in this sample group, including 200 males and 200 females. The frequency of W was 49.425%, of L was 48.300%, and of A was 2.275%. A was mainly distributed in the index fingers, and then in the thumb fingers. L was mainly distributed in the little fingers, and then in the middle fingers. W was mainly distributed in the ring fingers, and then in the thumb fingers. The frequency of same fingerprint pattern of a person's two hands was 16%. The frequencies of combination of the fingerprint patterns in one hand were OLW (65%)>combination of same types (26.125%)>ALO(4.5%)>ALW(4.375%). The frequencies of combination of fingerprint patterns on corresponding fingers were W/W(40.95%)>L/L(38.75%)>L/W(16.65%)>A/L(2.5)>A/A(0.9%)>A/W(0.25%). Conclusion: The frequencies of combination of fingerprint patterns on corresponding fingers were 80.6%, and the distribution of fingerprint patterns of Han juveniles is bilaterally symmetric.
