摘要： 为应用简便，本文对18—76岁正常成人104人(男67，女37)的X线正、侧位片上对颅外线或弧长等作了测量，并就其与颅腔体积的关系进行了认真的研究。用逐步回归分析法筛选出与推算颅腔体积的最佳因子为颅最大长(X1)、颅高(X2)，颅宽(X3)、颅矢状弧(X6)，它们之间呈正相关关系，其复相关系数R=0.74(女)±0.79(男)，均P0.0001。建立逐步回归方程式:
1.男:Y^=1.71X1+0.67X3+2.88X6-1788.02(cm3)
2.女:Y^=5.38X1+5.36X2+6.14X3-1541.73(cm3)
本方程可供推算成人颅腔体积使用。

关键词: 颅腔体积;逐步回归方程

Abstract: Lateral and anteroposteror aspect X-ray films were used to study the volume o f cranial cavity in 104 ( male 67, female 37) adults (ag ed 18_ 76). The measurments including cranial maximum length (X1 ) , cranial height ( X2 ) , cranial breadth (X3 ) , sagittal arc (X6 ) were found to be the significant factors in calculating the brain volume. The multiple correlative coefficient is R= 0. 74( female)— 0. 79( male). P 0. 0001. The stepwise regressive equation is then obtained as
1. male: Y^ = 1. 71X1+ 9. 67X3+ 2. 88X6- 1788. 02 (cm3 )
2. female: Y^ = 5. 38X1+ 5. 36X2+ 6. 14X3- 1541. 73 ( cm3 )
The equation may be applied to calculate the volume of cranial cavity o f the adult.
