摘　　要：介绍在大学物理实验中如何用迈克尔逊干涉仪测量、比较钠光和激光的相干长度。该方法不但丰富了实验内容而且使学生更深刻地理解了光的相干性、相干长度等概念,对激光的特性、激光与其它光线的不同之处也有所了解。Measurement and comparison of the interference lengths of sodium and laser with Michelsen＇s in terferomenter is introduced. The method not only broadens the experimental contents, but also deepens the students＇ understanding of the concepts on the optical interference and the interference length. It also makes students get familiar with the characteristics of laser, and the difference between laser and normal light.
