发射光谱测定法是我国化探工作中的一个重要分析手段，它具有快速和同时测定多元素等优点。近年来区域化探工作的开展把我国的化探工作推进到一个新的发展阶段，对光谱分析提出了更高的要求，传统的目视黑度比较法分析速度快，但精密度差，劳动强度也大；微光度计测光法分析精度较高，但操作复杂，速度很慢。因此，广大光谱分析工作者的迫切要
Emission spectrometry is an important analytical tool in geochemical exploration in China. It has the advantages of rapid and simultaneous determination of multiple elements. In recent years, the work of regional geochemical exploration has pushed the geochemical exploration work in our country to a new stage of development and put forward higher requirements for spectral analysis. The traditional visual blackness comparison method has the advantages of fast analysis, poor precision and labor Intensity is also large; Micrometer luminometer analysis of high precision, but the operation is complex, very slow. Therefore, the majority of spectral analysis workers urgently want
