本文着重介绍骨龄测定方法包括计数法、图谱法、计分法、计测法等及成年身高预测的方法，包括Ｇ－Ｐ图表法，ＴＷ２多元回归方程式等。经骨龄测定法对照研究认为，不同种族及地区骨成熟度标准有所不同，有些国外标准有一定偏差，不宜直接用于临床。因此应尽可能地制定本地区、本民族的骨发育标准 This article focuses on bone age determination methods including counting method, mapping method, scoring method, measurement method and adult height prediction methods, including G-P chart method, TW2 multiple regression equation. According to the bone age determination test, the standards of bone maturity in different races and regions are different. Some foreign standards have a certain deviation and should not be directly used in clinic. Therefore, we should make as much as possible in the region, the national bone development standards
