Summary form only given. This paper analyzes the emission spectra of atmospheric microwave Ar-air plasma and He-air plasma at the range of 200 to 1000 nm; diagnoses the free oxygenic radicals of them. Results reveal that, free oxygenic radicals occupy large proportion of all elements in the spectra of Ar-air and He-air plasmas. OH free radicals are strong near the 309-314 nm band compared with He...
This paper diagnoses the emission spectra of the Ar plasmas, which are excited at different pressure from 0.1 to 0.8 atm, and Ar-air plasma in open air with a unique microwave plasma generator-APMPS+JET system. The results demonstrate that the previous excited atom stations die out obviously as air is added; various factors play a part in the transform of atomic spectra lines, such as energy input,...
