【摘要】 <正> 本文运用多元线性回归分析的方法,对74例成人汉族男性胸骨（19～48岁）的形态变化与年龄的关系进行了研究。通过胸骨上选定的7个形态变化标志点,依其各自的形态变化规律,制定出相应的等级评分标准。根据此标准对74例胸骨标本进行了观察评分。然后将所得原始数据和年龄一起输入电子计算机,求出由胸骨形态变化,计算年龄的多元回归方程: =10.78+0.82X₁+0.85X₂+0.80X₃+0.38X₄+2.51X₅+0.64X₆+3.02X₇±2.45 经方差分析表明P<0.01,回归高度显著。本文提出的胸骨判定年龄的方法,在无名尸骨的法医学鉴定中,具有实用价值。更多还原

【Abstract】 The samples consisted of 74 Chinese male sterna of known age (19～48). observations were made at 7 characters of sternum.Based on the changes in these areas, the sterna were scored and the reg ressive epuation was made with computer to estimate biological age.
