摘　　要：目的研究广西侗族、京族、仫佬族男性手指纹型,以补充此三个民族肤纹学正常值数据库,并对纹型形成时胎儿指端胎垫形态进行推测探讨。方法印取男性指印资料400份(侗族200份,京族、仫佬族各100份)。参照《人类肤纹学研究观察的标准项目》分析资料并进行统计学处理。结果三民族男性手指纹型均以斗型、尺箕为主要纹型,桡箕和弓型纹出现率极低。斗型、尺箕及弓型的出现率在三个民族之间的差异有高度显著性(P<0.01);三个民族男性左右手各对应手指相同纹型出现率均较高;三个民族男性各指别的指纹嵴计数(FRC)均值从高到低,均依次为拇指>环指>中指>小指>食指。总指纹嵴计数(TFRC)差异无显著性(P>0.05);在手指纹型形成时,胎儿的指端胎垫均多为对称形隆起胎垫或顶部偏桡侧的非对称形中等胎垫,而对称形低平胎垫及顶部偏尺侧的非对称形中等胎垫较少见。结论三个民族男性被研究的指纹项目参数基本相似,亦存在部分民族间差异;在指纹形成时,胎儿的指端胎垫形态基本相同。Objective To consummate the data of ethnological dermatoglyphics in China, and to explore the characteristics of the male fingerprint parameters among Dong, Jing and Mulao nationalities in Guangxi, China. Methods 400 sheets of the male fingerprint rubbing by printing ink among Dong, Jing and Mulao nationalities （ the Dong 200 sheets, the Jing100 sheets and the Mulao 100 sheets） had been obtained from Guangxi, China. It had been analysed with statistics, referred to ＂The Standard Items In Study and Observation of Dermatoglyphics＂. Results Among the nationalities studied, both types of whorl （W） ＆ ulnar loop （Lu） had higher occurrence frequencies, both type radial loop （Lr） ＆ type arch （A） had lower occurrence frequencies. Occurrence frequencies of ＂W＂, ＂Lu＂and ＂A＂ differed significantly （ P 〈 0.01）. With high similarity among the three nationalities that the same fingerprint patterns appeared on the corresponding fingertips of left and right hands. Finger ridge count （FRC） ranking from high to low among the three nationalities showed as thumb 〉 fourth finger 〉 middle finger 〉 fifth finger 〉 fore finger. In total finger ridge count （TFRC）, there were no significant differences among the nationalities studied （ P 〉0.05）. It could be suggested that the main shapes of the fetal pads were the symmetric prominence or the unsymmetrical middle prominence which the top of the prominence were tilted radial side, but the symmetric plane upheavals or the unsymmetrical middle prominence which the top of the prominence were tilted ulnar side were seldom found, during the fingerprint patterns were configured among the three nationalities. Conclusion The parameters of the items of the fingerprint which had been studied are almost similar, yet there are some differences among the males of three nationalities. And the shapes of the fetal pads are homologous.
