摘要
对纳氏试剂分光光度法测定室内环境空气中氨质量浓度的不确定度进行了全面评定。建立了纳氏试剂分光光度法测定室内环境空气中氨质量浓度的不确定度数学模型,系统分析了测量方法测定结果不确定度的各影响因素,量化了各影响因素的相对标准不确定度,并计算出测量方法合成标准不确定度,最后得出扩展不确定度。
The report was about evaluation of uncertainty in determination of ammonia nitrogen in indoor environment with Nessler＇s reagent spcctrophotometry＇. Authors analysised various factors which effect uncertainty of measurement, with the mathematical model they got all values of them. Finally. combined standard uncertainty and expanded uncertainty were evaluated.
