This paper is to introduce the principle of interfering experiments with Yong＇s bi-slit,and how to simulate the experiments by using the programming skill of MATLAB.This experiment of simulation is simple and intuitive,and the simulation patterns being interfered by Yong＇s bi-slit can be easily obtained under different lengths of optical waves,widths of slit and distances of screen.It can be a basis for theoretical teaching of optics and experiments.%介绍了杨氏双缝干涉实验的原理及如何利用MATLAB编程技术对该实验进行仿真。该仿真实验方法简便、直观,可在不同光波的波长以及不同的缝宽和屏距下得到杨氏双缝干涉的仿真图样,从而为光学理论和实验教学提供了依据。
