摘　　要：塞曼效应是近代物理实验中非常重要的实验,但该实验原理比较抽象,仪器调节比较困难,因此采用计算机仿真该实验对于该实验的教学有着非常重要的意义。通过MATLAB编写程序,并在MATLAB GUI界面中模拟了通过等倾干涉圆环来展现塞曼分裂现象,观察到了不同状态的偏振光。在此基础上还测量了所用光源的荷质比,仿真结果较为理想。该仿真实验与教学相结合,可提高学生的科学素养和加深对该实验的理解。and the adjustment of instruments is difficult.Therefore,using comput-er simulation to simulate the experiment is of great significance for the teaching of the experiment.The program is written in MATLAB,and the Zeeman splitting phenomenon is simulated through the isoclin-ic interference ring in the MATLAB GUI interface.Different states of polarized light are also observed.On this basis,the charge mass ratio of the light source is measured,and the simulation results are ide-al.The combination of the simulation experiment and teaching can improve students' scientific literacy and deepen their understanding of the experiment.
