Abstract

Due to involving some advanced mathematics knowledge,the Fourier transformation connecting the real lattice and reciprocal lattice spaces is one of difficult points in teaching solid state physics. Based on the periodical characterization of crystal structure and the simple mathematical derivation,we attempt to give a detailed interpretation on the Fourier transformation process,in which the physical connotation is paid close attention.
