【摘要】 无汞定铁法是钢铁行业中的一种新方法。本文依据GB/T223.60-1999检测方法所规定的测量程序,分析了此方法的不确定度来源,讨论了影响铁含量的各种因素,结果得出测量的重复性实验是主要影响因素。计算出合成不确定度、扩展不确定度和测定结果报告。更多还原

【Abstract】 It is a new method of Fe analysis by using no hydrargyrum in steel.Based on the measure principle that prescripted of GB/T223.60-1999,the sources of uncertainty were analyzed,the infection factors of Fe content was discussed and the results showed that determination uncertainty was mainly due to measurement repeatability.The components of combined standard uncertainty,expanded uncertainty and determination result were calculated.更多还原
