用同步辐射X射线荧光分析法研究了小牛肩胛骨生长板软骨的元素组成。从软骨的静止、肥大和钙化区域获得X射线发射光谱：然后，每个元素以约10μ × 10μ的横向定义进行映射。有证据表明，一个均匀分布的元素在休息软骨相比，在局部浓度的变化，一些原子在肥厚钙化组织。Ca、Sr、Ni、Zn、S等元素在钙化前沿达到最大值，Cu元素分布均匀。一个锌的分布类似的含锌的酶碱性磷酸酶，钙化的关键酶，被发现。
The elemental composition of growth plate cartilage from calf scapula has been studied by means of SRIXE. X-ray emission spectra were obtained from the resting, hypertrophic and calcified regions of cartilage: then, each element was mapped with a lateral definition of about 10μ × 10μ. Evidence was found for a homogeneous distribution of the elements in resting cartilage compared to changes in local concentration of some atoms in the hypertrophic-calcified tissue. In this zone Ca, Sr, Ni, Zn, S, reach the maximal concentration at the calcification front while Cu shows a uniform distribution. A Zn distribution similar to that of the Zn-containing enzyme alkaline phosphatese, the key enzyme of calcification, is found.
