摘　　要：使用看谱镜计算机自动分析系统研究铁基合金中钴元素看谱分析用可见光谱,模拟Fe和Co元素的可见光谱图,摄制数字化彩色图谱。研究铁基合金中Co元素的Co486.79nm和Co535.21nm分析谱线组的特征,给出分析用谱图和半定量分析用强度标志。研究铁基合金中Co元素的看谱分析方法。结果可用于铁基合金和其他合金中Co元素的定性分析、半定量分析和牌号鉴别。Characteristic of visible light spectrum was studied on cobalt in ferroalloy by digital analysis system with grating spectroscope and prism spectroscope. The digital spectrums were simulated by computer and digital spec-trums were shot with digital analysis system. The researches were made on character of Co486.79nm and Co535.21nm line groups in ferroalloy. The analysis chart and intensity mark were obtained. The method was de- veloped for spectroscopic analysis of cobalt in ferroalloy and the investigation was made on the distinction of alloy mark. The research results can meet the requirements for qualitative analysis and semi - quantitative analysis on cobalt in ferroalloy, can be used to exactly examine alloy and avoid the commixing of material on spot.
