Abstract: Vacuum with pressure of several pascals is generated by a selfmade cylindrical tube. The emission spectra along the central axis of the tube of 65Pa air plasma and 14Pa air-CO2 plasma are observed, the strongest of which are recognized as the first and second positive system of N2. The vibration temperatures along the central axis are calculated using the relative intensity of the second positive system of N2.
Key words: plasma, emission spectrum, the second positive system, vibration temperature, DC glow dis?charge
