摘要: The intermediate phase (IP) between the α and β phases of quartz was studied by means X-ray diffraction topography a fine-beam Laue photography. It is an incommensurate characterized six modulation vectors which are nearly parallel to ± b i directions but rotated either positively or negatively around c -axis. regions with opposite rotation make domain structure. temperature dependence ( q ) precisely determined. “microtwins” model for IP criticized elementary theory our observations; mainly g , satellite intensities where reflection vector. A “configuration wave” more plausible. In addition, principles practical procedures in applying method quantitative study reflections presented.
