摘　　要：对GB/T 214-2007《煤中全硫的测定方法》中艾氏卡混合剂熔样-硫酸钡沉淀法测定煤中全硫测定结果的不确定度进行评定,通过对影响煤中全硫含量测定结果的不确定度分量进行分析和量化,探讨了测量结果不确定度的计算方法,并提出了改进实验方法的相应建议。Evaluation of uncertainty of results of total sulfur content determination in GB/T 214-2007 determination of the total sulfur in coal using Eschka mixing reagent melting sample-Barium sulfate precipitation method was done,through analysis and quantization of uncertainty component which affected the total sulfur content determination,calculating method of uncertainty was discussed,and as well as the suggestions for experimental method improving.
