 针对目前使用WGD 8A系列组合式多功能光栅光谱仪测量氢氘光谱波长的试验中对谱仪的标定问题，本文讨论了两种标定方法对试验结果的影响，一种方法是对多条标准谱进行一次大范围测量取平均修正值来对谱仪进行标定，另一种是针对每条待测谱线用相临的标准谱分别进行标定和测量。结果表明，针对每条待测谱线对谱仪进行分次标定和测量的方法，才能满足用线性内插法计算光谱值的条件，试验结果比一次大范围标定测量误差小的多。

Calibrating of Multifunction Grating Spectrograph and Measurement of Hydrogen and Deuterium Spectrum

For the issue of the calibrating of spectrometer in the experiment of hydrogen and deuterium spectrum measurement used the WGD-8A series composite multifunction grating spectrometer at present,the influence on the experimental result of two demarcation methods were discussed in two ways.One is calibrating spectrometer using the average of the corrected value on one time wide range survey to many standard spectra,another is separately calibrating the spectrometer and measuring hydrogen and deuterium spectrum...
