摘要
依据测量不确定度的评定原理和方法,分析了测量重复性、称样、滴定管等因素对硫氰酸铵容量法测定水泥中氯离子含量的不确定度的影响,并对水泥中氯离子含量测定结果的不确定度进行了评定。
Based on principles and methods of evaluation of measurement uncertainty,the measurement repeatability,sampling,burette and other influence factors for the determination of chloride ion in Cement by NH_4SCN titration method was analyzed. The uncertainty of measurement for the determination of chloride ion in Cement by NH_4SCN titration method was evaluated.
