摘　　要：介绍了空气-乙炔火焰原子吸收光谱法测定氟化锂中钾含量的测定过程中检测结果的不确定度的评价方法。建立了数学模型,并通过对测量过程中的各个不确定度分量的分析与量化,得出了测试结果的相对扩展不确定度,为准确测定氟化锂中钾含量提供可靠的理论依据。The uncertainty evaluation method of potassium content of the test results of lithium fluoride by air-aetylene flame atomic absorption spectrometry was introduced and the mathematical model was established.The relative expanded uncertain- ty of the test results was obtained by the analysis and quantification of the various components of uncertainty in the measure- ment, which provided reliable theoretical basis for the accurate determination of the potassium content of lithium fluoride.
