用汽油、煤油、柴油酸度测定法测定煤油的酸度,对测定过程中的不确定分量进行了分析和评定.测量不确定度主要来源于重复性测定、样品量取体积、消耗滴定溶液的体积和标准溶液的浓度的影响,从而对此测定方法的可行性和准确性进行了科学的判断.

Using gasoline,kerosene,diesel fuels-determination of acidity determining kerosene of acidity, the determination of components of uncertainty is analyzed and evaluated on. It was found that the major sources of uncertainty was from the determination of repeatability, sample measure volume, consumption of titration solution volume and the influence of the concentration of the standard.So the feasibility and accuracy of the method can be determined scientificly.
