中国人肱骨的性别鉴定

目的 建立中国人肱骨性别判定的方程。方法 测量了来自全国9省区的已知生前确切性别的103个个体的左右侧肱骨的12项测量指标,使用SPSS软件,对所获得的测量数据,进行男女性别间测量数据的t检验。剔除性别检验差异不显著的测量项目,使用Fisher判别分析方法,建立肱骨性别判定方程。结果 单一测量指标的性别判定方程20组,性别判别率为75.9％～89.3％;肱骨上端的性别判定方程2组,性别判别率为83.6％～85.7％;肱骨中段的性别判定方程2组,性别判别率为81.3％～83.9％;肱骨下端的性别判定方程2组,性别判别率为82％。完整肱骨的性别判别率,左侧87％,右侧90.9％,双侧肱骨的性别判别率为96.3％。结论 建立的肱骨性别判别方程,适用于中国人肱骨的性别判定。

The Sex discriminant analysis of Chinese humerus

Objective To construct the functions for sex discrimination with Chinese humerus. Methods 12 variables of both left and right were selected from 103 individuals with known sex from 9 different provinces. The data were then obtained. The test was performed between males and females by using SPSS soft ware. After eliminate those variables which sex difference was not obvious. Sex discriminating functions were established by using Fisher mothod. Results There were 20 discriminating functions by the measuring single Chinese humerus, Sex correct rate was 75.9% ~89.3%. They were 2 discriminating functions of the proximal humerus epiphysis. The sex correct rate was 83.6% -85.7%. They were 2 discriminating functions of the middle humerus diaphysis. The sex correct rate was 81.3 % -83.9 %. They were 2 discriminating functions of the distal humerus epiphysis. The sex correct rate was 82%. The sex correct rate of the whole left humerus was 87% and of the whole right humerus was 90.9%. The sex correst rate of both left and right humerus was 96.3 % . Conclusion The sex discriminating functions were new method for forensic science practice in China.
