【摘要】 研究89例中国汉族女性胸骨（11～61岁）上的8个部位的形态随年龄增长而变化的规律，并分别划分形态等级，然后采用多元线性回归和逐步回归分析方法，求出了由女性脑骨形态推算年龄的多元回归方程；对手柄—一体和／或体——剑突骨性融合的胸骨也建立了相应的方程。上述各方程经检验P＜0.01，r=0．99，SD在1．33～1．71岁之间。与国内外同类研究相比，本方法较为简便、准确，更具实用价值。更多还原

【Abstract】 Morphological changes of 8 characteristic points of 89 Chinese female sterna of known age (11-61 years) were observed- 4 - 6 grades of morphological changes of each point were set for eachcharacteristic and multiple linear regression models were worked out for estimating biological age offemal sternum. In case of fusion of manubrium with corpus and /or corpus with process xiphoideus,other regression models were worked out. The standard error of age estimation was about ± 1. 33-1. 71 years. Compared with foreigner’s, the present method is much simpler and more accurate.更多还原
