摘　　要：利用可见光谱数字化分析系统将铁基合金中钼元素Mo 603.07 nm和Mo 553.31 nm分析谱线组谱图转变为数字化的电子谱图,使用计算机自动分析代替人眼视觉判断,解决了谱图的量化分析和记录难题。对5种不同Mo元素含量的铁基合金标准样品进行数字化分析测定,探索在Mo 603.07 nm谱线组视场中分别选用Mo 603.07 nm谱线和Fe 600.30 nm谱线作为分析谱线和比较谱线进行定量测定的方法,数据显示分析谱线和比较谱线的强度比值与钼元素含量成正比关系。研究了数字化系统指导视场定位和谱线辨别的途径,降低技术难度并提高了快速分析的可靠性。结果表明,数字化技术保持快速分析特点的同时可以达到定量分析目的,有效解决了铁基合金中钼元素的快速定量分析及材料牌号鉴别问题。By application of visible spectral digital analysis system,the Mo 553.31 nm and Mo 603.07 nm spectral line group of iron-based alloy is transferred into the electronic spectrum of digitalization. And the replacing of the human visual judgment by computer aided analyses facilitates the spectrum quantification and solves the problems associated with the recording. The digital analysis of the five standard samples of the iron-based alloy with different content of Mo is done, and the quantitative analysis that employs the spectra of Mo 603.07 nm and Fe 600.30 nm as the analysis spectrum and comparison spectrum respectively is investigated. It is indicated that the content of molybdenum is proportional to the intensity ratio of the analysis and comparison of spectrum. The study of how to employ digital system to guide the visual location and the spectrum identification is an aid to the reduction of the technical difficulties and increment of the reliability of the quick analysis. The digital technique can achieve the quantitative analysis while it keeps the advantages of the quick analysis. Consequently, this technique provides an effective solution for rapid quantitative analysis and identification of trademark issues of iron-molybdenum alloy.
