摘要
关于劈尖干涉的问题表述中经常出现"一定范围内可看到若干条明(或暗)条纹",然而这些条纹是否完整,这个区域的边界处对应条纹的什么位置常常不是很明确,这给问题解答带来一定的不确定性。本文通过一个常见题目指出了存在的问题,并给出这类题目表述中应该注意的问题。
Some statements on interference in wedge-shaped film are often confused easy, for example, ＂we can see a number of bright（or dark） stripes within a certain range. ＂ However, It is not indicated clearly that the stripes are complete or not and where the boundaries of the area are located. These bring some uncertainty when solving the problems. This paper points out the existing problems through a common example, and gives the attention on the statements of this kind of problems.
