Auger electron spectroscopy was used to investigate the relative concentration of the calcium impurity at the external and fracture surfaces of a dense alumina after in vivo exposure for 6, 12, and 23 weeks. The Ca concentration at the external surface initially decreased, reached a minimum at 12 weeks, and increased thereafter. These results, were compared with the flexural strength, which decreased nearly linearly from 6 to 23 weeks.
采用俄歇电子能谱法研究了致密氧化铝在体内暴露6周、12周和23周后，其外表面和断裂表面钙杂质的相对浓度。外表面的钙浓度起初下降，在12周时达到最低值，此后又上升。这些结果与抗弯强度进行了比较，抗弯强度在6周至23周期间几乎呈线性下降。
