工业硫磺酸度测量不确定度的评估

Evaluation in the Measurement of Acid in Industrial Sulphur

应用不确定度评定方法对硫磺酸度测量进行不确度分析与评估,得出样品中酸度值的合成标准不确度和扩展不确定度。根据硫磺酸度测定的原理和步骤建立数学模型,对不确定度进行评定,找出主要影响因素,以进一步提高酸度测定的准确性,EXCEL表在评估中的使用,使评定中的计算更直观更灵活。

By analyzing the uncertainty of measurement of acid in industrial sulphur to obtain the synthetic standard uncertainty and expanded uncertainty of acid value. Based on the principles of acid measurement to build mathematical model, the uncertainty was evaluated, the main influential factors were found out to further improve the accuracy of acid measurement. Using Microsoft Excel, the calculation process of the evaluation was more intuitive and flexible.
