摘要/Abstract

摘要： 本文研究了碱金属、碱土金属氯化物载体对稀土谱线强度的影响。实验结果表明,加入这些载体后,由于等离子区稀土原子数增加,能大大提高稀土谱线强度,其效果原子线大于离子线,所用载体中以选用NaCl、KCl、CsCl为宜。

Abstract: The effect of the addition of alkali and alkali earth chloride carriers on the emission of rare earth has been investigated. The results show that addition of carriers causes the total number of rare earth atoms increased in plasma. This is due to the rates of evaporation increased and the residence time in the plasma prolonged. Therefore, the spectral intensities of rare earths are greatly enhanced. The incremental effect of the carriers on the intensities of the rare earth atom lines is greater than that of the rare earth ion lines, since the rare earth ionization percentage is decreased with the addition of the carriers.
