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。
In this paper, we measured the total length, stem length, body length, maximum width of the handle, maximum width of the body, maximum thickness of the handle and the maximum thickness of the handle of 85 Chinese sternums (male 52 and female 33). All the items were found to be significant Of the gender differences, but the overlap between the sexes is high, with a single difficult to accurately determine the gender. To this end, Fisher discriminant analysis was used to establish the discriminant function of the sex of the sternum with a discriminant rate of up to 90%. Taking into account the identification of the sternum sex, but also established the corresponding discriminant function. Compared with the foreign studies, the discriminant rate of this method is high and has more practical value.
