摘要
针对在发射光谱实验时，在发射光谱仪的毛玻璃框内观察到的两条由许多谱线组成的彩带的现象进行研究，用光栅公式解释了这些由原子的不同能极产生的谱线其波长变化的规律，并为光栅公式的应用提供了一个重要实例．
A research conducted on atom emission spectrum shows two colour belts,clearly made up of many spectral lines through the frosted glass. Optical grating formula is used to explain the changing patterns of the wave lengths of spectral lines produced by different atomic energy levels. It serves as an important example for the application of grating formula.
