应用 LIBS 技术对钢液中的锰元素进行监测，为了使监测结果更精确，提出选取分析线对的方法减小测量误差。选取基体元素 FeI433.705和 Fe II400.676作为内标元素的谱线，选取 MnI441.188和 MnII 423.514作为分析元素的谱线。当进行定标曲线建立时，分别将原子线与离子线配成线对，原子线与原子线配成线对，离子线与离子线配成线对建立相应的定标曲线，并将它们用于检验样品的定量分析。结果表明，定量分析时选择合适的分析线对，能使定标曲线的拟合度((92%，测量结果的相对标准差(1%。

Using the LIBS technique to monitor the manganese in molten steel, in order to make the quantitative a﹣nalysis result is more accurate, and put forward a method of selecting the analysis line to reduce the measurement er﹣ror. Selecting the matrix elements FeI433. 705and Fe II400. 676 as internal standard element line,Selecting MnI441. 188 and MnII423. 514 as element analysis spectral lines. When establishing the calibration curve,using a pair of atoms and ions line, a pair of atoms and atoms line, and a pair of ions and ions line to set up the corresponding calibration curve, and using them to inspect the quantitative analysis of the sample. The results show that the quantitative analysis choose a pair of suitable analysis line can make the calibration curve fitting is more than 92% , the relative standard deviation less than 1% of the measurement result.
