由此，本文首次提出了稀土元素在稀土金属间化合物中的能量传递模型，认为稀土与银金属间化合物的4f能级位于费米能级附近下方，部分局域化且与导带部分耦合。4f能级与导带能级之间的电子跃迁是稀土元素在Ag-BaO薄膜中传递能量的方式，也是光电发射增强效应的来源，而4f电子的光吸收截面随入射光子能量的增加而增大的特点则是"蓝强"现象的原因。

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.
