河北汉族青年指嵴纹数分析

Analysis of finger ridge count of Han young people in Hebei

目的：通过指嵴纹数的调查分析，为人类学和医学肤纹学提供正常参数。方法：无油墨法采集300例河北汉族青年的指纹，放大镜下计数。结果：总纹线数（TFRC）为148．37±39．56。各指指嵴纹数（FRC）中，拇指和环指明显高于其他各指，均为男性大于女性。随着对应指FRC差值的增加，频数减小，以差值t的频率最高，绝大部分差值在4以内，总共占78．54％。TFRC的频数分布近似正态。结论：各指别的FRC值具有明显的性别差异，左、右对应指FRC值分布具有对称性。

Objective： To study the finger ridge counts in Han young people in Hebei, and to provide normal parameters for anthro- pology and dermatoglyphics. Methods.. Fingerprint was obtained using ink method and counted by magnifier. Results： The average value of total finger ridge count （TFRC） was 148. 37 ± 39. 56. The mean value of FRC on the thumb and ring fingers was markedly more than that on other fingers, and that of males was markedly more than that of females. Along with the increasing deviation value of FRC between corresponding fingers, the variety trend of the frequency was gradually reduced, the frequency of the deviation value of 1 was at maximum, and an overwhelming majority （78.54%） of the value was less than or equal to 4. And The frequency distribution of TFRC was close to a normal distribution. Conclusion： The mean value of FRC on each finger had a significant difference between males and females, and the distribution of FRC in corresponding fingers is symmetric.
