摘要
通过建立数学模型,分析肉丸中硼砂比色法测定的过程中影响测定结果的不确定度及其影响因素。同时对各分量标准不确定度也进行了分析和计算,得出了吸光度值、试验重复测量导致的标准不确定度是不确定度来源的最主要影响因素。最终通过合成和扩展得出了某肉丸中硼砂含量为(110±16)mg/kg。
The uncertainty and influenced factors for determination of borax in ball by colorimetfic method had been analyzed by mathematical expressions.At the same time, the components of the standard uncertainty were analyzed and calculated. The results indicated that the mail uncertainty source covered the uncertainty induced by ultraviolet absorbance and the uncertainty induced by measuring repeatability.Then the results were combined and expanded, thus the content of the borax in any balls was （ 110±16）mg/kg.
