还原型钼蓝酸盐光度法测定钢铁及合金中酸溶Si含量的不确定度评估

EVALUATION OF UNCERTAINTY FOR DETERMINATION OF ACID-SOLUBLE SILICON CONTENT IN IRON,STEEL AND ALLOY BY THE REDUCED MOLYBDOSILICATE SPECTROPHOTOMETRIC

对钼蓝光度法测定钢铁中Si含量的不确定度的产生原因进行分析,并分析了一个钢样中硅含量测定结果进行了不确定度的评定。

This paper analyses the cause of uncertainty for determination of acid-soluble silicon content in iron, steel and alloy by reduced molybdosilicate spectrophotometric, meanwhile it evaluates the uncertainty against the testing result of silicon content in a sampling steel.
