摘要:

An electric probe was used for measurements of the normal cathode fall in a glow discharge in flowing CO2laser mixtures (CO2:N2:He=4.5:13.5:82 and 5:20:75) for uncooled copper, stainless‐steel and tungsten cathodes. The results imply that the cathode fall value in the mixture is governed mainly by the presence of carbon dioxide.
