• A study is made concerning the spectra of some elements in steel observed by the discharge in various atmospheres which are composed of oxygen, nitrogen and argon.<BR>The obtained results are summarized as follows:<BR>(1) The spectral-line intensity is not affected by the total pressure of atmosphere but by the partial pressure of oxygen or nitrogen.<BR>In other words, as it is related to oxidation of metals and also mutually related to excitation of molecular spectra, the spectra of elements are restrained by appearance of oxides and CN molecules.<BR>(2) On the discharge in nitrogen atmosphere below 760 mmHg, it is found that the stability of discharge column is most excellent at about 200 mmHg.
