85 Chinese sterna(52 males and 33 females)were measured.All 7 measurements were found to have very significant sex differences.However,the overlapping rate between both sexes is very high.It's difficult to determine sex with single measurement.By using Fisher' method,the sex discriminant functions were calculated which can determine sex 90% correctly.For the purpose of sexing bro- ken sternum,some other diseriminant functions were also calculated.Compared with foreigner's,this study has higher discriminant rate and wider practical use.

135 Chinese adult tibiae (69 males, 66 females)were measured. Statistic test shows that all 12 items of measurement have significant sex differences. For the purpose of determining sex from fragmentary tibia, 17 sex diseriminant functions for fragmentary tibia were calculated by means of stepwise discriminant analysis and Fisger's method. The diseriminant rate ranges from 79.3% to 821.4%. The present study shows that the proximal epiphyseal breadth,the distal epiphyseal breadth and the circumference at the level of the nutrient foramen have the most important value in identification of sex they can determine sex alone 79.3—80.2% correctly.
