【 摘 要 】

Optical emission spectroscopy and mass spectrometry measurement were used to study a gas mixture glow discharge of He and N2at total pressure of 2.0 Torr, a power of 10 W and a flow of 16.5 l/min. The emission bands were measured in the wavelength range of 200 to 1100 nm. The principal species observed were N2+(B2Σ+u→X2Σ+g), N2(C3Πu→B3Πg), and He, which agree with mass spectrometry measurement.
