摘要
用K2Cr2O7容量法测定铁精粉中TFe含量,详细分析了不确定度的来源,对各分量所引入的标准不确定度和相对标准不确定度进行了评定,求得测量结果的合成相对标准不确定度和相对扩展不确定度分别为0.19%和0.38%。
The uncertainty for the determination of TFe in the Iron ore samples by K2Cr2O7 volume was studied.The origin of uncertainty has analyzed,the compose relative standard and spread uncertainty were gained as 0.19% and 0.38%,respectively.
