全自动定氮仪测定大米中蛋白质含量的测量不确定度分析

Analysis of Uncertainty Measurement of KJELTEC System 2300 Measuring of Protein in the Rice

通过KJELTEC2300型全自动定氮仪对大米中蛋白质的重复性试验结果,分析影响测量结果的各个因素,对各个分量进行计算和合成,求出合成不确定度和扩展不确定度。

The protein in the rice is tested repeatedly, each factor of influence on the uncertainty of the determination is analyzed, and calculation and combination of each component are carried out, the combined standard uncertainty and expanded uncertainty are got.
