摘　　要：运用Matlab软件,对双缝衍射和双缝干涉、单缝衍射的光强分布和谱线特征进行了数值模拟,绘出实验中难以观察到的光强分布图,比较出双缝衍射与双缝干涉及单缝衍射的联系与区别。This paper used the Matlab software, a numerical simulation of the double-slit interference and double-slit diffraction intensity distribution was made. It also drew in experiments which was difficult to observe in the light intensity distribution. Compared the relation and distinction between the double slit diffraction, double slit interference and single slit diffraction.
