摘要/Abstract

摘要： 本研究所用材料为已知性别、已知年龄的东北地区汉族成人干燥颅骨。应用Fourier变换，将额骨矢状弧的形态转变成Fourier极数，然后应用多元逐步判别分析求得性别判别函数，判别符合率达到90.10％。对31例已知性别汉族成人颅骨盲测，正确率达到84.21% (男性) 和83.33％ (女性) 。研究表明，颅骨的大小和年龄对本方法的判别结果无显著影响。

Abstract: The sex difference of mid-sagittal frontal arc was quantitatively analyzed in present paper. The samples used in this study are dried alult skulls of known sex and known age in thenortheast China. The mid-sagittal frontal arc is expressed with Fourier Series by Fouriet Trans-form. The discriminant function (DF) for sex determination was devised by means of multi-ple stepwise discriminant analysis. As a result, the predictive rate is 90.10%. Blind test on 31known sex skulls showed that the accuracy ra es were 84.21% for 19 males and 82.33% for 12 females. The study indicated that the age and size of skull have no effect on the sex diagnosis.by this method.

Key words: Skull; Sex determination; Discriminant analysis
