摘　　要：探讨了在迈克耳孙干涉仪反射镜M2前加入不同厚度的玻片,对干涉条纹级数变化的影响.实验表明,对于不同的反射镜M2到透镜的距离,改变反射镜M2前玻片的厚度,存在干涉条纹的疏密变化从不断陷入变为不断冒出的临界位置.通过实验得出了临界位置与两反射镜间距的关系.This study discussed the effect of thickness of the glass inserted in front of the mirror of Miehelson interferometer. The experiments show that for different distance between the lens and the mirror, there exists a critical position that makes the interference fringes to move in a reversed direction. Through the experiment we have found the relationship between the critical position and the distance between the lens and the mirror.
