摘　　要：根据杨氏双缝干涉的理论,利用MATLAB语言编写程序对该实验进行计算机仿真,该仿真程序能够绘制单色光和非单色光的杨氏双缝干涉图样和光强分布曲线,并且同步计算出相应的条纹间距和对比度;此外,设计了仿真实验的图形用户界面,用户可以根据显示的杨氏双缝干涉模型更改实验参数,直观地分析各参数的变化对于干涉结果的影响,为光学的理论分析与实验教学提供了方便,为相关课件的设计提供了新的途径。According to the theory of Young＇s Double Slit interference,a program using MATLAB to simulate it with computer is presented.The program can display the interference pattern and distributing curve of intension when the incidence light is monochromatic or non-monochromatic,and the corresponding interval of interference fringe and contrast can be figure out,furthermore,a GUI（Graphical User Interfaces） of the simulation experiments is designed,user can input the parameter according the model of Young＇s Double Slit Experiments and analyze their influence to the result of interference.It makes easy to teach optical theory and experiment and offers a new way to design the related CAI.
