The matric expressions of equivalent points of crystal space and corresponding reciprocal space are applied to the discussion of structure factor types.
In this paper the matrix expressions of equivalent points of microcosmic symmetrygroups of crystal unit spaces and their corresponding reciprocal spaces are applied in the dis-cussion of the systematic absence law of the crystal s X-ray diffraction.
A new Constructive Method for Four-Index Orientation of Hexagonal Crystals was drawn out based on four-index reciprocal lattice.
利用四指数倒易点阵建立了一种四指数晶向的简单直观的作图方法,并从理论上给予证明。
The equivalent solid sphere have same radius of the original coating shell, using reciprocity theorem(RT), the effective conductivity of composite were obtained, it compare agree with effective medium approximation.
