| 摘 要： | 本文测量了85例国人胸骨(男52,女33)的全长、柄长、体长、柄最大宽、体最大宽、柄最大厚及体最大厚七个项目,发现所有项目都具有非常显著的性别差异,但两性间重迭率较高,用单项难以准确判定性别。为此,采用 Fisher 判别分析法建立了判定胸骨性别的判别函数,判别率最高达90%。考虑到残缺胸骨的性别鉴定,亦建立了相应的判别函数。与国外研究相比,本文方法判别率较高且更具有实用价值。

| Abstract: | 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. |
