收集中国北方28具(男15、女13)汉族成年人尸体材料,调查了尸体身高、胸骨全长、胸骨柄长、及胸骨体长的均值,并计算了胸骨的长度与身高的相关系数。胸骨全长、胸骨柄长及胸骨体长与身高的相关系数,男女合计分别为0.8630、0.7122、0.8395,表明皆为高度相关。其中男、女分别计算男性分别为0.7157、0.5789、0.5669,女性分别为0.6111、0.5630、0.6122,表明除男性胸骨全长高度相关外,其余皆为中度相关。在相关的基础上,又算出由胸骨长度估计身高的9个回归方程式。由胸骨全长推算身高的回归方程式,较由胸骨柄长和胸骨体长推算身高的回归方程式,有较高的相关系数和较低的标准估计误差。由胸骨体长推算也较由胸骨柄长推算为佳。由骨的长度来推算身高,所用骨的长度越长,相关系数越高,标准估计误差越低,其推算的身高越接近于实际。
The body material of 28 adult (15 males and 13 females) Han adults in northern China were collected and the mean body length, total sternum length, sternum length and sternum length were investigated. The correlation coefficients between sternal length and height were calculated. Sternal length, sternum length and sternum length and height correlation coefficient, male and female total respectively 0.8630,0.7122,0.8395, indicating that all are highly relevant. Among them, male and female were respectively calculated male 0.7157,0.5789,0.5669, female 0.6111,0.5630,0.6122, respectively, indicating that there is a moderate correlation except for the total length of male sternal bone. On the basis of the correlation, we calculated the regression equation of height estimated from the length of the sternum. The regression equation of the height of the sternum calculated from the total length of the sternum than the length of the sternum and the length of the sternum to calculate the height of the regression equation has a high correlation coefficient and a lower standard error. Calculated by the length of the sternum is also better than the length of the sternum. The length of the bone to calculate the height, the longer the length of the bone used, the higher the correlation coefficient, the lower the standard error of estimation, the estimated height closer to the actual.
