基于光栅衍射的晶体X射线衍射缺级的理论基础和实验研究

以光栅衍射缺级理论为切入点对晶体X射线衍射缺级的现象、产生的根源进行了理论分析，得出：(1) 晶体X射线衍射缺级存在的可能性在于某些晶体材料晶胞的几何结构因子为零;(2) 在复式格子晶体或具有某种特殊缺陷的晶体的X射线衍射图样中存在缺级是这方面实验研究的方向。这些结论在材料物相、材料结构类型和不完整性分析等方面具有一定的参考价值。

Theoretical Analysis of the Spectral Line Missing Stage in Crystal X-Ray Diffraction Based on the Diffraction of Grating

In the present paper, the theoretical analysis was performed of the phenomenon and causes of the spectral line missing stage in diffraction of grating and crystal X-ray diffraction, and their application was discussed. It was concluded that the crystal X-ray diffraction probably lies in the fact that the geometrical structure factor of unit cells of some crystal materials is zero, and secondly, the spectral line missing stage in diffraction could be an interesting subject in the crystal X-ray diffraction research. On the whole, these conclusions may provide an important reference to the study on material phase, structure and intact analysis etc.
