摘　　要：目的：对藏族拉萨青少年指骨各指节长度及宽度进行X线测量，探讨其性别差异及其与性别判别的相关性，为法医及人类学提供判别率较高的性别判别式。方法：随机选择健康的藏族拉萨青少年1680人（男840人，女840人），进行左手前后位X线拍片，同时测量身高，将所得数据用SPSS17．0软件进行统计学分析处理。结果：男性与女性各指骨长度均无差异，男、女指骨宽度性别差异均有统计学意义，唯环指近节宽和环指远节指骨宽在男女间差别无统计学意义。同时将指骨与性别的判别分析为第l组，指骨和身高与性别的判别分析为第2组，应用Fisher法逐步判别分析得出2组判别式分别为Y=2．603X1＋1．733X8＋9．987X22＋1．057X23＋0．742X10＋1．896X11-107．480，Y=2．292X1＋2．448X8＋8．709X22-0．319X23＋1．685X10＋0．516X11-92．976；Y-1．160X8＋8．713X22-4．611X23-0．847X10-0．981X11＋2．231h1-178．514，Y-1．849X8＋7．488X22-5．820X23＋0．001X10-2．253X11＋2．148h2-159．747。第1组判别率分别为80．2％、86．1％，第2组判别率分别为81．5％、86．1％，如Y（女）〉Y（男）即判为女性，反之Y（男）〉Y（女）则判为男性。结论：以上N,N式对法医学及人类学的性别鉴定简单实用，具有较高参考价值。Objective： To measure the length and width of phalanges of Tibet adolescents, and provide correlationship with gender and stepwise discriminant formulas for sexual diagnosis. Methods： A total of 1 680 healthy Tibet adolescents （M840, F840） were included. Their left hands were taken X-ray films on posteroanterior position. The length and width of each phalanges and their heights were measured. All data were analyzed by SPSS17.0 software. Results： It was found that for the length of each finger, there were no sexual differences. But for the width, there were sexual differences. Meanwhile, the discriminant analysis on phalanx and gender was performed in Group 1, and phalanx, height and gender discriminant analysis in group 2. The Fisher method was used in two groups. Y=2.603X1＋1.733X8＋9.987X22＋1.057X23＋0.742X10＋1.896X11-107.480,Y=2.292X1＋2.448X8＋8.709X22-0.319X23＋1.685X10＋0.516X11-92.976;Y-1.160X8＋8.713X22-4.611X23-0.847X10-0.981X11＋2.231h1-178.514,Y-1.849X8＋7.488X22-5.820X23＋0.001X10-2.253X11＋2.148h2-159.747. The rates of the first group were 80. 2% and 86. 1%, and those of the second group were 81.5% and 86. l% （Y （F）〉 Y （male） that ruled women, whereas Y （male）〉Y （F） the penalty for the men）. Conclusion： The above formulae are useful for sexual diagnosis on forensic medicine and anthropology.
