摘要
讨论晶体对X射线衍射时,经常用到布喇格方程2dsin(?=j(?),其中2dsin(?)是相邻两束衍射光的 光程差,它为何不含介质的折射率n?本文根据介质对光波的色散与吸收的经典理论,对此问题做了讨论。
When people discuss the diffraction of the X-rays, the Bragg equation is often used. In the equation, 2dsin(?) is the light range difference of two neibouring diffractions. Then, why doesn' t the equation contain the refraction index of the medium? In this paper, this problem is discussed.
