摘要：
This paper derives the physical meanings of peak position, peak width and height of an X-ray diffraction peak from the analyses of the Bragg’s equation, the Scherrer’ s formula and the principle of peak intensity calculation. The geometric characteristics of an asymmetric peak are clarified by means of experiment. The relationships between peak shape and domain size/ lattice strain have been verified by geological events. Therefore this paper integrates the physical meanings of all 5 basic parameters for an X-ray diffraction peak. Applications of these 5 parameters are exemplified.
