应用软X线推断国人耻骨年龄

ESTIMATING PUBIC AGE BY PHOTOGRAPH OF SOFT X-RAY

对男性１１８副、女性１０８副、１０－６０岁国人耻骨样本应用软Ｘ线进行拍照。根据其内部结构随年龄增长而发生的形态变化规律，采用多变量统计分析法，研制出数量化赋分值标准。用该标准取得的观测数据，使用数量化理论Ⅰ和逐步回归数学模型，借助电子计算机技术进行统计分析，建立了推断耻骨年龄男女各自两个方程。经１３例实际案件中应用，其结果达到了设计要求，方程有一定应用价值．

This article reports the estimation of male and female pubic age by the Photographh of soft X-ray. The pubic bones of 118 male and 108 female Chinese withh exact birthdate from 10 to 60 years old were collected. According to the relationship between variations of Pubic bones mircostructure and age, a new quantification standard was designed by multi-variant statistical analysis, and the data observed from this criterion was analysized by stepwise regression quantification I theory. TWo equations were set up for the estimation of male and female pubic age by means of electronic computer.
