烦人的二级光谱线

BORING SECONDARY SPECTRAL LINE

本文利用光学知识说明了二级光谱线难以寻找的原因 ,从而要求在实验过程中 ,除了耐心、仔细外 ,在调节仪器的时候还要做到“一适中 ,二清晰 ,三合一”。

This paper explains the causes that the secondary spectral ilne are very hard to find through the optical knowledge and during the experiment.We must also mind No.Dne-medium,No.Two-,No.Three-combination in additionto the patience and carefulness when want to adjust the instrument.
