摘要
建立了示差扫描量热法(DSC)测定防老剂D纯度的数学模型并推导出不确定度计算公式;通过对公式中各变量的分析,计算了各变量的不确定度,最后计算出合成不确定度。
A mathematical model was established for the measurement of the purity of antioxidant D by DSC and a formula was deduced for the calculation of uncertainty. The uncertainty of each component was calculated through analyzing various variables of the formula. Finally, the combined uncertainty of the purity of antioxidant D was obtained by synthesizing the uncertainties of various components.
