摘要
根据ＬＥＣＯＣＳ－４４４红外碳硫仪的结构和原理，对测定难熔铁合金中硫的含量时产生拖尾现象的原因进行了分析和探讨，并提出了具体解决办法，提高了分析速度和分析结果的精密度与准确性．
Based on the principle and structure of LECO CS-444 infrared carbon and sulfur detector,this paper Presents an investigation in the causes of extension of integral time in the determination of sulfur in infusible ferroalloys by infrared absorption,and puts forward the relevant suggestions to get rid of above phenomenon so as to make the analysis quicker and the results be of high precision and accuracy.
