摘　　要：使用新型的WSM-T-Ⅱ型台式迈克尔逊干涉仪可以测量氦氖激光波长，传统的数据处理方法是逐差法，计算量大，既繁琐又容易出错。用Matlab软件的编程法处理实验测得的数据，程序运行后可以直接得到氦氖激光波长及相应的误差分析，无需进行运算，准确而快捷，是大学物理实验教学中实验数据处理的一种新方法。
The use of WSM-T-type II desktop Michelson novel interferometer can measure the helium neon la-ser wavelength,the method of data processing is the traditional difference method,a large amount of calcula-tion,tedious and error prone. The measured data by programming method in the treatment of experimental Mat-lab software,running the program can be directly obtained from the analysis of He Ne laser wavelength and the corresponding error,no need of operation,accurate and fast,and it is a new method of experimental data pro-cessing of physical experiment teaching in university.
