摘 要：<正> In order to eliminate influence of the carriers on the evaporation of rare earth elements in DC arc,a de-vice which introduces axially the sample aerosol has been designed to study the effects of controlled-atmos-phere,discharge current,electrode polarity and introduction direction of aerosol on the emission of rare earthelements in DC arc discharge.The influence of various matrices and carriers on the line density and excitationcondition of rare earth elements have also been studied,then the related excitation mechnism is proposed.
