摘要:

本文以X射线荧光光谱法测定铝土矿中Al2O3为例,详细论述该方法在分析过程可能产生的不确定来源,并对各分量不确定进行了评定。通过研究可知,X射线荧光光谱法测定铝土矿中Al2O3时不确定来源有许多,主要有测量不确定度引入的不确定度、标准样品引入的不确定度、称量误差导致的不确定度等方面,本文通过计算出各分量的不确定度,对各个分量不确定度进行定量分析,最后合成得到测量结果的扩展不确定度。

The study discussed the source of uncertainty about measuring the Al2O3 of bauxite by X-ray Fluo-rescence Spectrometry in detail; moreover, we assessed the uncertainty of all components possibly. According to the research we could know there were several reasons that caused the uncertainty about measuring the Al2O3 by X-ray Fluorescence Spectrometry, such as the method of measurement, standard reference materials, weighing error, etc. The uncertainty of each compo-nent was calculated and analyzed quantitatively; the extended uncertainty of measurement results was obtained from synthesis of each uncertainty source.
