国人胫骨的测量及其性别判别分析

为积累国人资料，本文对长春、通辽两地出土的１２７副胚骨（男７１，女５６）进行了胚骨最大长、胚骨全长等２６项指标的测量，计算出胫骨中部断面指数和胚骨指数等４项指数及其分型，进行了侧别、性别及地区比较，并用胫骨最大长等７项因素进行了Ｆｉｓｈｅｒ法性别判别分析，得出５个判别式．结果显示：除个别测量项外均无显著性侧别差异，但均具有显著性性别差异，部分项目存在显著性地区差异；判别分析中判别正确率（７８．３％－８２．３％）介于美国白人与黑人之间。

THE MEASUREMENT OF THE TIBIA AND ITS SEXUAL DIAGNOSIS IN CHINESE

One hundred and twenty-seven Pain of tibias of chinese were measured. They were collected from ChangchUn and Tongliao DistrictS, Liaoning Province. Twenty-six measurementS including the length, width, circumferece, diameter and angle were measured and four indices were calculated. The results show that most measurementS have no statistic difference between tWo sides, but the sex-difference of all the measurements are highly sighficant (p<0.01). The data were analysed by using Fisher's method. Five discriminant formulae for sex determination with accuraCy teSt on the same series of tibias Produced correct results in 78.3% to 82.3% of cases.
