早在六十年代,光电看谱定量分析技术国内已有使用。1978年国产WKD-1型仪器的成批生产使该法在国内得到了较广泛的应用,特别是分析钢铁中低合金元素效果显著。但是,WKD-1型仪器在技术上还存在以下问题: 1 在钢铁中分析低含量的Cu、Al、Ni、W和较高含量元素(如0.5～2%Al、1.5～5%Cr)时,测量数据不稳定,常限于半定量或近似定量分析的水平。
As early as the sixties, photoelectric quantitative analysis of the spectrum has been used in the country. The batch production of homemade WKD-1 instruments in 1978 made the method widely used in China, especially for the analysis of low-alloy elements in steel. However, the WKD-1 instrument technically has the following problems: 1 When analyzing low content of Cu, Al, Ni, W and higher content elements (such as 0.5-2% Al, 1.5-5% Cr) in steel , The measurement data is not stable, often limited to the level of semi-quantitative or approximate quantitative analysis.
