原子吸收光谱法测定粗铅中铜的测量不确定度评定

摘要

By adopting national standards to determine the copper content of crude lead, and analyze each of the uncertain-ty component of measurement, the combines uncertainty and extended uncertainty were calculated, and the main sources of uncertainty were found out, in order to reduce the measurement error, ensure the accuracy and effectiveness of the measure-ment.%本文采用国家标准方法－原子吸收光谱法测定粗铅中铜元素的含量，并且对引起测量结果的各个不确定度分量进行了分析，计算合成不确定度和扩展不确定度，确定引起不确定度的主要来源，以此达到减少测量误差的目的，从而保证了测量结果的准确性。
