本文研究了102例国人成年颅锥体角度,计算了颅径与锥体角之间的平均值之相关系数,其中颅长(g-op)、颅长减颅宽(g-op—eu-eu)和锥体角之间的相关系数分别为(-0.288)和(-0.326),表明负相关度比较密切。其结论是。颅长径越长,则锥体角越小,反之亦然。国人锥体角平均度数为52度(精确数为51.635°)。两侧相等者占46.6％,不等者为53.4％,但性差和侧差均不显著,即t值分别为0.74和1.51,P>0.05。计算了从颅长和长、宽差值推算锥体角的回归方程式,其回归系数均为(-1),t值分别为2.99和3.44,P<0.01和0.001。回归方程推算的结果提示:以颅长17厘米或长、宽径差3厘米以及锥体角52°为基数,当颅长或径差比17或3厘米增加1厘米时,则锥体角减小1度,反之应增大1度。
In this paper, the adult cranial pyramidal angles of 102 Chinese were studied, and the correlation coefficients between the average cranial diameter and the pyramidal angle were calculated. Among them, g-op, g-op-eu- eu) and cone angle (-0.288) and (-0.326), respectively, indicating that the negative correlation is relatively close. The conclusion is. The longer the long axis of the skull, the smaller the cone angle and vice versa. The average cone angle of Chinese people is 52 degrees (the exact number is 51.635 °). Equal on both sides accounted for 46.6%, ranging from 53.4%, but the sex difference and lateral difference were not significant, that is, t values were 0.74 and 1.51, P> 0.05. The regression equation of the cone angle deduced from the difference of length, length and width of the skull was calculated. The regression coefficients were both (-1), with t values of 2.99 and 3.44 respectively (P <0.01 and 0.001). The result of the regression equation suggests that when the cranial length or diameter difference is increased by 1 cm compared with 17 or 3 cm when the cranial length is 17 cm or longer and the width difference is 3 cm and the cone angle is 52 °, Small 1 degree, on the contrary should increase 1 degree.
