| Abstract: | Adopting the direct chart of the cause and the effect, analyzed all kinds of uncertainty sources in the process of the determination of total iron content in the ores and their influences on the uncertainty. Established the effective mathematical model. The uncertainty estimation of the determination result was carried out by the caculating of the relative standard uncertainty step by step and the compounding wholly. |
