通过分析杨氏干涉的发生现象以及对杨氏干涉的光程差公式的推导，指出了文献[1-6]中对光程差的近似计算过程存在的一个不妥之处．通过不同的方法和具体数据比较证实了本文提出的观点，并给出了较精确的计算方法．该结论有益于学生掌握光程差的近似计算．

A deficiency for optical path difference calculating in Refs. [1-6] is studied through analyzing phe nomena of Youngs interference and deriving the formulation of optical path difference. The existence of this deficiency is proved by contrasting specific experimental data from different experimental method. An accurate method is given to calculate the optical path difference, which is helpful for students.
