摘要: 在固体物理学课程中,由于涉及到一些高等数学知识,理解联接正格子和倒格子空间的傅里叶变换过程一直是教 学难点之一.本文从晶体结构的周期性特征出发,并结合简易的数学推导,对傅里叶变换过程进行了详细的解读,并且对其中 的关键步骤给出了凸显物理内涵的解释.

关键词: 固体物理, 正格子空间, 倒格子空间, 周期性, 傅里叶变换

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.

Key words: solid state physics, real lattice space, reciprocal lattice space, periodicity, Fourier transformation
