为了阐明生理性过速或过缓发育的性别特征,作者对在青春发育期及其前期男女形态成熟速度进行了研究。对256名6～8岁儿童(男144、女112)按身高、骨化水平、恒牙数目的标准综合判定生物年龄,对142名10～13岁儿童(男82、女60)按动态观察过程中的身高及其年增加、骨化水平、第二性征出现等指标的综合,判定成熟速度。 In order to elucidate the gender traits of physiological hyperactivity or over-growth, the authors studied the rate of male and female morphogenesis at puberty and its pre-emptive period. A total of 142 children aged 10 ~ 13 years (male 82, female 60) were dynamically observed on 256 children aged 6 ~ 8 years (male 144, female 112) according to the criteria of height, ossification and number of permanent teeth The height of the process and its annual increase, the level of ossification, the emergence of secondary sexual characteristics and other indicators of the comprehensive, determine the maturity rate.
