目的探讨人手皮纹学的更多规律和特点。方法对自愿参加手皮纹检查的171名学生进行手皮纹印制油墨图,再对指纹及指皮嵴数、总指嵴数(TRC)、t-三叉及t-距比(tPD)、atd角、a-b嵴数、手掌褶类型等进行观察、统计和比较,并结果既往报道不同地区汉族皮纹进行比较。结果①漩涡状和双箕斗嵴线旋转方向以逆时针多见(98.89%,90.38%);②男女TRC,a-b嵴数,tPD和atd角差异无统计学意义;③食指中弓形纹和桡箕多见,所占比例分别为50.00%和63.27%;④双箕斗以大拇指所占比例高,占50.00%;⑤指纹类型左右手完全对称的比例为17.143%;⑥鄂东地区与冀南地区指纹构成比,各指纹分布规律差异无统计学意义(P>0.05),仅手掌褶类型差异有非常显著意义(P<0.01);⑦比较了鄂东与宁夏TRC,差异无统计学意义,但标准差相差很大。结论手皮纹在更细致的观察和同类研究中发现一些有意义的规律和特点。
Objective To explore more rules and characteristics of human hand dermatoglyphics. Methods A total of 171 students who participated in hand-stick test were hand-printed with ink on their prints. The number of fingerprints and finger crest, total ridge count (TRC), t-triad and t-distance ratio atd angle, ab crest number, palm fold type were observed, statistically compared and the results of the previous reports of different regions of the Han skin pattern for comparison. Results ① The rotational directions of whirlpool and double-skip ridge lines were more common (98.89%, 90.38%) in anticlockwise direction; ② There were no significant differences in TRC, ab crest number, tPD and atd angle between male and female; The proportion of double-skip with high thumb, accounting for 50.00%; ⑤ fingerprints left-right symmetry ratio of 17.143%; ⑥ East Hubei Province and Hebei (P> 0.05). There were significant differences in the types of palmar fold (P <0.01). ⑦ Compared TRC between Edong and Ningxia, the difference was not statistically significant, However, the standard deviation varies greatly. Conclusion Handkerchief has found some interesting rules and features in more detailed observations and similar studies.
