摘要
根据GB/T742—2008测量漂白硫酸盐针叶木浆中的灰分,建立数学模型,找出不确定度来源。依据JJF1059.1—2012对测量不确定度的各个分量进行计算,最后得到合成不确定度和扩展不确定度。通过比较各分量的大小,找出影响灰分测量的重要因素。
According to GB/T 742-2008 of measuring ash in bleached sulfate coniferous wood pulp, built a mathematical model and found out the origin of uncertainty. According to JJF 1059.1-2012, calculate the standard uncertainty of each component. Finally gain uncertainty. By comparing the value of each component, the combined standard uncertainty and the expanded find out the mainly influential factors of the ash test.
