通过模拟实验，研究了具有不同作用的４种光谱添加剂对铁矿粉末样品分析的影响。实验结果表明，最佳载体效应和最佳缓冲效应所对应的添加剂质量分数一般不同。
Through simulation experiments, the effects of four kinds of spectrum additives with different effects on iron ore powder samples were analyzed. The experimental results show that the best carrier effect and the best buffer effect corresponding to the additive mass fraction is generally different.
