摘　　要：采用平面光栅光谱仪测量未知波长,并以钠原子、汞原子光谱为例,通过对其观察、测量和分析,加深对金属原子中外层电子与原子相互作用以及自旋与轨道运动相互作用的了解。对光谱用CCD多分析器进行分析和波长测量。In this paper, plane grating spectrograph was used for the measurement of unknown wavelength, for example, sodium atom （Na） and mercury atomic （Hg） have been chosen for the spectroscopy research. By means of observation, measurement and analysis of spectroscopy, we can deepen the understanding of interaction between the outer electrons of the metal atom and atom, and interac- tion between spin and orbital motion, by analysis with a CCD muhi-channel spectrum analyzer and wavelength measurement.
