本文通过对736名世居青藏高原（海拔3000－4000米）藏族7－18岁青少年学生手部χ光片的调查，探讨了各掌骨长度与身高增长间的关系及规律。结果表明：虽然手部五块掌骨长度不一，但每块掌骨的增长与身高的增长趋势都非常相似，二者间均存在着较高的正相关关系，而且各掌骨与身高间的相关程度难分高低。各掌骨长度／身高指数随年龄增长均显示缓慢增大趋势，数值仅呈相对恒定。本文提出了以各拿骨长度推算高原藏族青少年身高的回归方程。
In this paper, 736 Tibetans (3000-4000 meters above sea level) Tibetans aged 7-18-year-old hand pupils χ light film to investigate the relationship between the length and height of each metacarpal and the law. The results showed that although the metacarpal of the five hands were different in length, the growth of each metacarpal was very similar to the growth of height. There was a high positive correlation between the two metacarpal bones and the height of each metacarpal Difficult to distinguish the level. Each metacarpal length / height index showed a trend of increasing slowly with age, the value was only relatively constant. In this paper, we propose a regression equation to calculate the height of adolescent Tibetan Plateau by the length of each bone.
