用FTIR、TG-DTA、XRD等对产物形成过程及结晶学特征进行了研究，考察了合成样品与Sm0.2Ce0.8O1.9的化学相容性；利用碘滴定法测定了该系列产物中Fe元素的平均表观化合价和氧的非化学计量值。

It was found that the DAPS shift of La was associated with 4f energy change under the influence of 3d hole-4f electron interaction, and with the change of polarization energy, while the change in DAPS line shape of Ce reflected its valence fluctuation.

并发现La的DAPS峰位的移动主要和3d空穴-4f电子互作用下的4f能级变化有关，另外还和极化能的变化有关。而Ce的DAPS峰形的变化可以反映Ce特有的化合价涨落现象。这一工作深化了对稀土DAPS的认识，有利于APS在以后的稀土研究中的应用。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。
