摘要 为了更好解释多缝夫琅禾费衍射的实质,利用Maple软件编程实现了对多缝夫琅禾费衍射的计算机仿真.绘制出其相应的衍射图样和光强分布曲线,通过改变可调参数详细分析了多缝夫琅禾费衍射的光强分布特点和缺级现象的影响因素.研究结果表明仿真实验与实际实验结果一致,程序简单,仿真效果直观形象,方便教学应用. To better explain multiple-slit Fraunhofer diffraction in real terms, the multiple-slit Fraunhofer diffraction was simulated by using the Maple software. Their diffraction patterns and light intensity distribution curves were drawn. By changing adjustable parameters, the light intensity distribution features and the influential factors of the multi-slit diffraction missing order phenomenon are analyzed in some detail. The research shows that the results of numerical simulation are completely coordinated with actual experiments, and the arithmetic is easy to be realized and convenient in teaching due to its intuitionistic simulation effects.
