摘　　要：按常规是用分光计测量光栅常数的,比较麻烦,本文介绍一种新方法,即用眼晴直接观察的方法测量光栅常数。虽然有一定的误差,但在误差允许范围之内,可方便使用。Usually, we measure grating constant by spectrometer,but it’s very complicated. A new method is given in this article. Grating constant can be directly measured by eyes. Although there is some error in this method, it’s very convenient if some error will be allowed.
