摘要
运用傅里叶交换，求出衍射光栅的空间频谱函数，讨论了光栅方程，谱线半宽度，谱线强度等九个问题。
By means of Fourier transform,this paper has obtained spatial frequency spectrum function of diffraction grating,and discussed grating equation and other eight problems. The method is simple and direct,physical sence clear and definite,physical picture distinct.
