通用型聚苯乙烯树脂中残留苯乙烯单体的不确定度评定

Ucertainty evaluation of residual styrene monomer in polystyrene

本文依据JJF1059-1999测定不确定度评定与表示[1],对通用型聚苯乙烯树脂中残留苯乙烯单体测定的不确定度评定,分析了各不确定度分量,建立了数学模型,并计算其测定结果的扩展不确定度。

According to JJF1059-1999 evaluation and expression of uncertainty in measurment,this paper evaluated the uncertainty of determination of residual styrene monomer in polystyrene . We analyzed the uncertainty components ,established the mathematical model ,and calculated the un-certainty of the determination .
