针对迈克尔逊干涉实验中测出的He-Ne激光的波长值总是比真实值偏大的问题，分析了用迈克尔逊干涉仪测量He-Ne激光波长时的实验误差来源，发现实验光路调整的不理想以及仪器读数装置中残留的螺纹空程差是导致λ值偏大的主要原因。在此基础上提出了相应的改进办法，并且对测量不确定度进行了合理的估算。

In this paper the error source of the measurement of the wavelength of He-Ne laser with a Michelson interferometer is analyzed,especially aim to the problem that the measurement result is usually larger than the true value of the wavelength. We found that the main error comes from the defect in the light system and the backlash error remained in the Michelson interferometer. An improving method is put forward and the measure-ment uncertainty is reasonably evaluated.
