应用图像分析仪测定了52名青年手的掌侧投影面积,各指掌侧面积的平均值,以中指最大(13.40cm~2),拇指其次(12.47cm~2),食指(12.03cm~2)与环指(12.00cm~2)近似,小指的掌侧面积最小(8.63cm~2)。全手掌侧总面积平均145.20cm~2。指掌侧总面积平均58.52cm~2,占手掌侧总面积的40.30％。手掌面积平均86.69cm~2,占手掌侧总面积的59.70％。按stevenson公式,根据身长和体重,计算出体表面积的估计值,进而求得全手掌侧投影面积占身体表面积的0.93％。经计算机处理,求得手长、手宽、身长、体重、体表面积估计值与手面积的相关系数,说明上述5个变量与手面积的相关均非常显著。本文还建立了由手长、手宽推算手掌侧投影面积的回归方程。
The average size of the palmar area and the area of each finger of 52 young people were measured by the image analyzer. The maximal middle finger (13.40cm ~ 2), the second thumb (12.47cm ~ 2), the index finger (12.03cm ~ 2) ) And the ring finger (12.00cm ~ 2) approximate, the smallest area of the little finger palm side (8.63cm ~ 2). The total palm-side area of an average of 145.20cm ~ 2. The average palmar side of the total area of 58.52cm ~ 2, accounting for 40.30% of the total palm-side area. The average palm area of 86.69cm ~ 2, accounting for 59.70% of the total palm-side area. According to stevenson formula, according to body length and weight, calculate the estimated body surface area, and then get the entire palm side of the projected area of 0.93% of the body surface area. The correlation coefficient of the hand length, hand width, body length, body weight, estimated body surface area and hand area obtained by computer processing shows that the correlation between the above five variables and hand area is very significant. In this paper, a regression equation of hand-side and hand-width projections is also established.
