以优碳钢、铝合金和铜合金光谱标样为样品，进行了激光显微发射光谱实验研究，标定了部分元素的分析谱线，对其谱线相对强度和再现性进行了分析和讨论。
The samples of excellent carbon steel, aluminum alloy and copper alloy were used as samples to study the laser emission spectrum. The analytical spectra of some elements were calibrated and the relative intensity and reproducibility of the spectra were analyzed and discussed.
