摘　　要：根据三棱镜对光的色散原理,提出了用分光计观测原子光谱并用最小偏向角对各谱线进行标记,比较光谱的位置,从而用内插法测得了未知谱线的波长。实验结果表明:使用三棱镜最小偏向角尺度分析法测定波长有其可操作性和一定的应用意义。This paper focuses on observing the atomic spectroscopy by spectrometer and applying the method of minimum deviation angle to marker each spectrum line as the position of comparison of spectra, and then obtain the wavelength of unknown spectrum line by means of interpolation method. These results show that minimum deviation angle of triangular prism is an excellent method to determine the wavelength.
