应用软X线推断国人耻骨年龄

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。

ESTIMATING PUBIC AGE BY PHOTOGRAPH OF SOFT X-RAY

This article reports the estimation of male and female pubic age by the Photographh of soft X-ray.
