本文通过对空气—乙炔火焰原子化过程的全面分析,根据原子化诸参数的性质和它们之间的定量关系,在合理简化条件下,推导出了火焰原子化方程。并相应地建立了原子化度的计算公式。利用该公式所计算的Ca的原子化度值与文献报导值十分相近。同时还计算了Cu、Zn、Ag、Cd、Mn等元素在吸收区中的原子密度n_a,最后计算了他们的理论灵敏度。其结果与实际灵敏度比较一致,两者之差都在三倍以下。
Based on a comprehensive analysis of the flame-atomization process of air-acetylene, a flame atomization equation is deduced under reasonable simplification conditions according to the properties of atomization parameters and their quantitative relationship. Correspondingly, the formula of atomization degree is established. The calculated degree of atomization of Ca using this formula is very close to that reported in the literature. At the same time, the atomic density n_a of Cu, Zn, Ag, Cd, Mn and other elements in the absorption region were also calculated, and their theoretical sensitivities were calculated. The results are consistent with the actual sensitivity, the difference between the two are less than three times.
