摘要: 用分光光度计测定水发产品（水发海参）中甲醛含量，分析和评估了影响测定结果的各种因素，建立测量不确定度数学模型，对各不确定度进行量化处理，认为影响水发产品中甲醛含量测定结果的主要因素是试验重复性操作的过程、标准工作液及蒸馏液浓度的精确度。

Abstract: Formaldehyde content in waterishlogged food products (water risen sea cucumber) was measured by using spectrophotometer, and the various factors affecting measurement were analyzed and assessed. Then the mathematical model of uncertainty was established to systematically calculate the uncertainty of each components and the uncertainty of the influencing factors. The results showed that the main factors affecting formaldehyde content measurement in waterishlogged food products were the repetitive operating process in test, the accuracy of the standard operating fluid and the accuracy of the concentration of distillate.
