本文选择健康的汉族本科学生及小学生为调查对象,用X2检验法分析指纹白线的出现频数。其中青年组(本科生)男女各58名,儿童组(小学生)男43名,女生41名,结果显示22.77±4.17%的受检男生及34.34±4.76%的受检女生出现指纹白线。男女间指纹白线出现频数的差别具有显著性(P<0.001)。说明指纹白线的出现与性别有关。分析结果还显示,双手较单手指纹白线出现频率高(P<0.01);儿童较青年指纹白线出现频率高(P<0.01);指纹白线出现频率是否也与年龄及对称性有关,需进一步探讨。
In this paper, healthy Han undergraduates and primary school students were selected as the survey subjects, and the frequency of appearance of white lines of fingerprint was analyzed by X2 test. Among them, 58 were male and female in the youth group (undergraduates), 43 were male children and 41 were female students. The results showed that 22.77 ± 4.17% of the boys examined and 34.34 ± 4.76% of the boys Check the girl appeared fingerprinted white line. The difference in the frequency of white lines between male and female fingerprints was significant (P <0.001). Explain the appearance of white lines on the finger and gender. The results of the analysis also showed that the frequency of fingerprints was higher (P <0.01) than that of single-hand fingerprints. The frequencies of white fingerprints of children were higher than that of young fingerprints (P <0.01) Symmetry, need to be further explored.
