本文基于谱线强度公式,研究了碱金属和碱土金属氟化物对各种元素谱线强度的影响,也讨论了这些元素的谱线强度增强的机理。所得结果表明,电离度的降低是易电离元素的谱线强度增强的主要因素,对某些难电离的元素,谱线强度的增加,主要是因使用氟化物,电孤等离子体中,元素的浓度增加所致。某些难挥发的元素浓度的增加,是由挥发过程加快和扩散过程变慢所引起,而易挥发的元素浓度的增加,则由扩散过程变慢所造成。
In this paper, the influence of alkali metal and alkaline earth metal fluoride on the spectral intensity of various elements was studied based on the spectral line intensity formula, and the mechanism of enhanced line intensity of these elements was also discussed. The results show that the decrease of ionization degree is the main factor for the enhancement of the line intensity of the easily ionized elements. For some hardly ionized elements, the increase of the line intensity mainly results from the use of fluoride, Increased concentration. The increase in the concentration of some non-volatile elements is caused by the acceleration of the volatilization process and the slowing of the diffusion process, while the increase of the more volatile elemental concentrations is caused by the slower diffusion process.
