| 摘 要： | 利用可见光谱数字化分析系统将铝合金中镁元素Mg518.36nm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6种不同镁元素含量的铝合金标准样品进行了数字化分析测定,探索了选用Mg518.36nm作为分析谱线,分别选用Cu510.55nm和Fe510.75nm作为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镁元素含量呈正比。研究了数字化系统指导视场定位和谱线辨别的途径,降低了可见光谱分析的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的目的,能够有效解决铝合金中镁元素的快速定量分析及材料牌号鉴别问题。 |

| Abstract: | Using digital visible spectrum analysis system, the visible spectrum line of Mg 518.36 nm in Al-based alloy sample was transformed into digitized electronic spectrum, which replaces the human visual judgment by computer automatic analysis and solves the difficult problems of spectrum recording and spectrum quantification. In this work, the digital analysis of six Al-based standard alloy samples with different content of Mg has been performed. Using spectra of Mg 518.36 nm as the analysis spectrum line, Cu 510.55 nm and Fe 510.75 nm as comparison spectrum lines separately, quantitative analysis has been made. The results indicate a proportionality relationship between the content of magnesium and the intensity ratio of the analytic and comparative spectrum lines. The development of employing digital system to guide the visual location and the spectrum identification aids in reducing the technical difficulties and improving the reliability of the quick analysis. The research results indicate that the digital technique achieves quantitative analysis and keeping the advantage of the quick analysis. Consequently, an effective solution for rapid quantitative analysis and identification in analysis of Mg in Al-based alloy is provided. |
