摘要：
A method, based on the Doppler broadening-dependent absorption width and the ionization degree measured by the ratio of relative atomic and ionic absorbance in cathodic sputtering glow discharge (CSGD) plasma with aluminum-magnesium alloys as cathodes,is proposed. The experimental reveals that the plentiful magnesium ions in the plasma under the conventional discharge conditions,of the atomizer do influence the analytic working curves. Corrected method is derived and factors which result in magnesium ionization degree are disscused.
