为了解和建立土家族中小学生这方面的形态学指标,采用适合中国人的Stevenson标准公式,对土家族中小学生的体表面积进行了调查研究。结果显示:1)土家族中小学生体表面积值随着年龄增长而增长,且其增长速度男女生均可分为匀速增长期、快速增长期、速度减缓期3个不同时期;2)男女生体表面积曲线出现双交叉现象,即11岁时女生体表面积值超过男生,14岁时男生的体表面积又超过女生,15岁以后二者体表面积值的差异逐渐增大,表现出显著性差异。
In order to understand and establish the morphological indicators of primary and secondary school students in Tujia, we investigated the body surface area of primary and secondary school students in Tujia Minority with the Stevenson standard formula suitable for Chinese. The results showed that: 1) Tujia primary and secondary school students body surface area value increases with age, and its growth rate of boys and girls can be divided into uniform growth period, rapid growth period, the rate of slowing period of three different periods; 2) male and female body surface area The phenomenon of double crossover occurs in the curve, that is, the body surface area of girls exceeds that of boys at the age of 11, and the body surface area of boys exceeds that of girls at 14 years old. The difference of body surface area values gradually increases after 15 years of age, showing significant differences.
