摘　　要：本文介绍了极谱法测定化探样品中钨的不确定度评价方法,并根据标准曲线建立了测定钨含量不确定度的数学模型,较全面的评定了测量结果不确定度。测量结果不确定度表明待测物制备过程中样品消解、测量过程中校准曲线及测量重复性所产生的不确定度占的比例较大。This paper introduces the method of determination of uncertainty of tungsten in geochemical samples by polarography.According to the standard curve established the mathematical model of uncertainty of determination of tungsten content,a comprehensive evaluation of the uncertainty of measurement results.The uncertainty of the measurement results indicates that the uncertainty of the sample digestion during the preparation process,the calibration curve in the measurement process and the uncertainty of measuring repeatability are relatively large.
