硅钼蓝分光光度法测定铁矿石中二氧化硅含量测量不确定度评定

Assessment of the uncertainty in measurement of silica in iron ore with silicon-molybdenum blue spectrophotometry

应用测量不确定度评定理论,结合日常工作和实验方法,分析硅钼蓝分光光度法测定铁矿石中二氧化硅含量的影响因素,计算和评定测定过程各不确定度分量,最终给出分析结果的测量不确定度.

The factors affecting the measurement uncertainty of silica in iron ores with silicon-molybdenum blue spectrophotometry were determined using the uncertainty theory and the routine experimental method. The uncertainties in individual measurement stages were calculated and assessed, and finally summed up to give the resultant uncertainty of the whole measurement.
