摘　　要：为了进一步提高耻骨推断年龄方程推广使用价值，在原方程454副样本基础上又增加146副，共600副（男、女各300副）。观测项目（形态特征）由男女各9个减为各8个。有效赋分标准，男性增加5个；女性增加4个。每项中0改为1。使用数量化理论1和逐步回归数学模型，取得8个方程、6个推断年龄表。应用时可根据不同性别、不同年龄组，选用不同推断年龄表，使用不同标准差。比原方程，提高了实际应用价值。In order to promote extension and improve practical value of age estimation equation by pubic bone, we added 146 pairs of samples to the previous 454 pairs, summing up to 600 pairs (300 pairs of man and woman respectively). The observing items reduced to 8 from 9 for man and woman, meanwhile, the effective score criteria were added 5 for man and 4 for woman (table 1 and 4). Score 0 was changed to 1 in each item. Appling the quantitative theroy 1 and stepwise regressive mathematics model, equations and 6 age estimation tables were obtained. In practical use, according to the different sex and age stage, corresponding age estimation table and different standard error were selected. Compared with the previous equation in which the same standard error was used for people aged 14 ～ 70 years old, the practical value of the current equation was remarkably improved.
