摘　　要：本文讨论了多缝夫琅禾费衍射的光强分布特点,编写Matlab程序绘制光强分布曲线,分析了多缝夫琅禾费衍射缺级现象的影响因素,与单缝衍射因子和缝间干涉因子有关.This article has discussed the light intensity distribution features of the multi-slit diffraction. We have drawn the intensity distribution curve by Matlab, and analyzed the impact of the multi-slit diffraction missing order phenomenon, which relates to the single-slit diffraction factor and the interference factor among slits.

关 键 词：多缝衍射 缺级 单缝衍射因子 缝间干涉因子
