摘要
本文以700名汉族儿童为对象,对掌轴三叉t的位置,用三个参数进行研究。以atd角和tpD作为纵向参数,以横向指数(dt:at的长度比)作为横向参数,并与过去文献资料进行对比。鉴于儿童手掌正在发育过程中,作者对数据进行了回归分析,分别求出三个参数与年龄有关的回归方程,为今后开展儿童皮纹学研究提供了参考数值。
Three parameters were used to study the position of palmar t-triradius in 700 normal Han nationality children. The atd and tpd were taken as longitudinal paramters for description of the position and the transverse index (dt/at)as transverse parameter. The measured data were compared with those in previous literature. Statistical treatment of these data showed that significant linear correction existed between the parameter and age, so three regression equations were respectively deduced on the basis of primary data. These results may serve as reference data for studing the dermatoglyphic patterns of children.
