浙江地区汉族三百例手纹的分析研究

A DERMATOGLYPHIC STUDY OF THE HANDS OF 300 PEOPLE OF HAN NATIONALITY IN THE ZHEJIANG REGION

本文报道汉族正常的手纹图型。指纹的斗型、尺箕、桡箕及弓型的频率分别为51.67％、43.4％、2.83％及2.1％。t％及atd角的均值分别为17.7％及40.28°。手掌有二个掌轴三叉的占3％。ab纹嵴数均值39.03,男比女高(p<0.01)。ab间的距离为2.21cm。无a、b三叉缺失,c、d三叉缺失者10.3％。指间三叉占6.33％。A线止于鱼际的占9.33％,证明了右手掌纹比左手横向水平。鱼际区(T/I_1)及小鱼际区的真实花纹出现率分别为11.3％及20.5％。双手I_2、I_3、I_4区的花纹各为1％、4.67％及57％。正常型掌褶占88.2％。

This paper presents a detailed dermatoglyphic study of the normal hands of Han nationality which comprises 150 males and 150 females.1. Frequencies of finger print patterns W, Lu, Lr, A are 51.67%, 43.4%, 2.8396 and 2.1% respectively. The male whorls are more abundant than female, while the arches appear with a greater frequency in females than in males (p &lt; 0.01).2. Mean t% is 17.7%. Mean atd angle is 40.28°. The existence of two separate axial triradii (tm) amounts to 18 hands with a frequency of 3%.3. The ab ridge count is 39.09 with a higher number in males than in females (p &lt;. 0.01). The mean value between a and b triradii is 2.21 cm. The normal values for ad ridge count and ad distance are 87.55 and 5.1cm respectively. The ratio of ab distance to ab ridge count is 0.057cm4. No a and b triradii absence, while the frequency of absence of c or d triradi is 10.3%. The interdigital triradii (I2, I3, I4) total up to 6.33%.5. The A line terminates in 9.33% of the 600 hands at the thenar area with the right hands having much less frequency (2.33%) than the left (16.33%). If the hypo-thenar area is divided artificially into proximal and distal halves, the A line to the distal half is much more frequent at the right hands (55%) than that at the left (12.33%). Right hands in group comparison with left show a greater degree of transversality of con- figuration.6. Frequency of true patterns in palmar thenar area (T/Ii) is 11.3%, that in palmar hypothenar area 20.5%. Frequencies of bilateral pattern in I2, I3, I4 are 1%, 4.67% and 57% separately.7. The distribution of different patterns of the palmar crease is the normal pattern, 88.2%; the simian line pattern, 1%; the transitional I pattern, 4.2%; the transitional II pattern, 3.5% and the pattern of Sydney, line, 3.2%.
