裕固族皮纹学初步研究

本文研究了甘肃裕固族青少年儿童346人的皮纹学特征,报道了斗、箕、弓各型指纹的频率,指纹指数,总指嵴数,a-b嵴数,通关手出现率,掌纹真实花样等8项皮纹学参数和主线止区的分布比例。并作了性别、手别、族别及人种间的比较。结果表明,裕固族既具有蒙古人种的皮纹特征,也有一些白种人的皮纹特点,这可能暗示着裕固族有白种人的血统。

The results from both sexes are as follows: The frequencies of finger pattern W, L and A are 51.24%, 46.66% and 2.22% respectively. The main TFRC is 147.18, and the main a-b TRC is 40.69. The frequencies of true patterns in palmar thenar, palmar hypothenar, interdigital area I2, interdigital area I3, interdigital area I3/I4, interdigital area I4 are 9.21%, 25.47%, 1.57%, 19.17%, 21.64%, 56.63% respectively.
