通过对用离子选择电极法测定铜精矿中氟含量的研究,在建立方法数学模型的基础上,分析了测定过程不确定度的主要来源,并计算了各不确定度分量,经合成得到相对标准不确定度,从而求得扩展不确定度。
Based on the research on the determination of fluorine in copper concentrate by ion-selective electrode method, the main sources of uncertainty in the determination process are analyzed based on the mathematical model of the method. The components of each uncertainty are calculated and the relative Standard uncertainty, so as to obtain expanded uncertainty.
