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 % .
