摘要
按照GB/T 6739.6规定,采用F检验法比较了5种铜磁铁矿中铜含量分析方法的精密度,得出了5种分析方法精密度显著性差异情况,给出了选择分析方法的原则。
The precisions of five analytical methods for the determination of Cu contents in copper magnetite samples were compared using F-test method based on GB/T 6739.6. The results indicated that there were significant differences among these five methods. A principle for the selection of analytical methods for Cu detection was given.
