讨论了寿命长、成本低廉的稀土彩色日光灯在基础物理实验中应用的意义，利用光栅结合分光计和光栅光谱仪观察到黄色日光灯在可见光范围有8条线状光谱，谱线丰富，可替代汞灯和钠灯．用迈克耳孙干涉仪确认黄色日光灯的相干长度达0．4mm，可替代溴钨灯完成白光干涉实验．

The application of long service life ,low cost color fluorescent lamp based on rare earths in fundamental physics experiments was discussed .Using grating spectrometer ,eight spectral lines were observed in the visible range of yellow fluorescent lamp ,which meant that it could replace mer-cury lamp and sodium lamp .This yellow fluorescent lamp ,with a coherent length of 0 .4 mm ,as measured by Michelson interferometer ,could also replace bromine tungsten lamp in white light inter-ference experiment .
