光电直读光谱仪分析铝及铝合金中Fe元素含量的不确定度评定

Evaluation of uncertainty in determination of Fe in aluminum or aluminum alloy for analyzing by photoelectric direct-Reading spectrometry

对光电直读光谱测定铝及铝合金中Fe元素含量不确定度的产生原因进行了分析,并对Fe含量测定结果的不确定度进行了仔细地评定,从而明确了提高准确度的方法。

The spectrometry direct - reading determinates the Fe element content in aluminum and the aluminum alloy uncertainty production reason has carried on the analysis, and caxried on to the Fe content determination result uncertainty has evaluated carefully, thus was clear about enhanced the accuracy the method.
