Abstract:
Limited by the spatial structure of one-atmosphere surface dielectric-barrier-discharge plasma in air,a grating monochromator is used to make spectral measurement on the plasma.Spectral lines are detected in various conditions of power frequency and electrode gap.Experimental results show that: the spectral lines detected in various conditions are almost in the same shape and the plasma mainly consists of nitrogen discharge;the strength of spectral radiance is linear to frequency;the strength of spectral radiance reaches its maximum when the electrode gap equals to zero and declines symmetrically and linearly when the electrode gap deviates from zero in both positive and negative direction;and that each peak covers a fixed percentage out of the whole spectral line’s area regardless of the change of the power frequency and the electrode gap.
