由胸骨长度估算中国北方成年人身高的回归方程 总被引:2,自引:0,他引:2
调查了中国北方28具(男15、女13)汉族成年人尸体身高、胸骨全长、胸骨柄长和胸骨体长的均值,并计算了胸骨的长度与身高的相关系数。除男性胸骨全长高度相关外,其余皆为中度相关。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。 相似文献

从中指骨长度推算身高的研究 总被引:2,自引:0,他引:2
作者对近年在华南地区收集的,已知生前身高的汉族成年男性骨骼的中指骨近节、中节进行了测量。用直线回归方程、多元回归方程对从中指骨长度推算身高进行了研究。并用50例国人骨骼标本对这些推算身高的方法作了检验。结果表明,中指骨与四肢大型长骨,以及从中指骨长度推算身高的直线回归方程与多元回归方程,对推算身高的价值都是相同的。 相似文献

以牙磨耗度和牙指数推算牙齿年龄的多元回归方程式的研究 总被引:3,自引:0,他引:3
本文对97例华南人M~I的磨耗度、牙指数和年龄三者之间的关系进行了深入探讨。并由此而提出以牙磨耗度和牙指数为两个变量的三元回归方程。比较分析结果表明,三元相关系数高于其它二元相关系数,三元回归方程的标准估计误差低于其它二元回归方程的标准估计误差。因而,以三元回归方程式比单纯以牙指数或牙磨耗度作为变量的二元回归方程式估计年龄准确。 相似文献

目的本文在于探讨用锁骨的某一项测量指标建立推算其最大长的回归方程,然后可根据所得值间接推断死者的身高.方法本地收集的75例成年男性尸体,按体质人类学测量方法,用人体测量仪器对其锁骨的各项指标进行测量,所得值用SPSS统计学软件分析处理.结果相关分析和回归分析,表明锁骨的各项指标与锁骨的最大长之间均有着非常显著性的关系存在,P<0.001.进而建立了相应的回归方程.结论在实际工作中,如果能测得锁骨残段的某一项指标,就可用所建立的回归方程推算其最大长,这在法医人类学上具有一定的参考价值. 相似文献

Based on the materials of 50 Han male adult cadavers collected in South China in recent years,we have calculated the constants (a) and the regression coefficients (b) for estimating the stature by long bones as well as the coefficients of correlation (r) between the length of long bones and the stature. The value of the correlation coefficients varies within 0.516.913. This indicates that the degree of correlation is high. On this basis we have also calculated ten regression formulae by which the stature can be estimated. The correction value 0.6 mmX (age—30) is used to correct the error caused by age.<br>The results of the calculation by humerus and fibula,humerus plus radius and femur plus tibia are better than those by other bones. The regression formulae made in the present article can be used to estimate the stature of South Chinese. 相似文献

28 adult cadavers from north China were studied. The average value of the stature, the total length of sternum, the length of the manubrium sterni, the length of the body of sternum were measured. The coefficients of the correlation between the average length of the sternum and the stature were calculated. The coefficient of correlation between the total length of the sternum, the length of the manubrium sterni, the length of the body of the sternum and the stature are 0. 8630, 0. 7122 and 0. 8395 respectively. It shows that the correlation between them is rather high. But in the males the coefficients of correlation are 0. 7157, 0. 5789 and 0. 5669 respectively; while in the females they are 0. 6111, 0. 5630 and 0. 6122 respectively. Nine regression formulae from the average length of sternum and the stature were computed.<br>The relationship between stature and total length of sternum reveals a higher coefficient of correlation and a lower standard error of estimation, as comparied to that between stature and length of the manubrium sterni and that between stature and length of the body of the sternum. The reconstruction of stature from the length of the body appears more reliable than that from the length of the manubrium of the sternum. 相似文献

Diaphyseal lengths of the humerus, radius, femur and tibia of upper-middle class White children between two months and 11 years of age show positive allometric growth, indicating substantial shape or proportional change. The segments of the lower extremity display greater allometric increase than the humerus and radius; variation in relative growth within each extremity is small and inconsistent. Sex differences are consistent, with slightly greater proportional increases demonstrated for boys. The results suggest that absolute intralimb variation in growth, following a disto-proximo growth or maturity gradient, is due to initial differences in size or scale and not to differences in patterns of growth. Developmental variation between extremities is due to scaling plus variation in relative growth patterns. 相似文献

Based on the observation of the antero-posterior roentgenographs of the knee of 1361 Han students born iii Xian, the time and rate of epiphyseo-diaphyseal fusion of the long bones forming the knee joint were obtained. The results were compared with the reports of other authors. The causes of increasing stature in recent years were discussed. 相似文献

The materials investigated were 91 maxilhary first permanent molars of Southern Chinese.<br>The method of area measurement of structures of the teeth on longitudinal section is applied. The crown-chamber index was calculated according to the following formula:<br>Crown-chamber index = [ (area of enamel + area of pulp chamber) / (area of dentine of erown) ]×100<br>The regression formula to estimate age is:<br>Y=72. 32-0: 442X.<br>(X=crown-chamber index) 相似文献
