山东蒙阴褐色金刚石塑性变形信息的对称性分析

hrough a large number of photographs, this paper compares and describes brown diamonds , Mengyin Country, Shandong Province, from five sides of the original stone microscopic characteristics, characteristics of the original stone cathode luminescence, slicing microscopic characteristics, slicing orthogonal polarization characteristics, and characteristics of slicing cathode luminescence. In an attempt to take a preliminary analysis on these that will be caused by plastic deformation diamond counterparts such as brown bands, the extinction of a series of information with counterparts. And provides some evidence for the plastic deformation characteristics of Shandong Mengyin brown -diamond. The plastic deformation of symmetric information analysis can provide a reference for the studies of Shandong Mengyin brown-diamond plastic deformation.
