不确定度在果蔬罐头固形物含量检测中的应用

The application of measuring uncertainty to testing the content of solid things in fruit and vegetable cans

按照测量不确定度评定的通用规则,对以电子天平测定果蔬罐头固形物含量的测量的不确定度进行了评定,测量结果和不确定度评定结果为(60.79±0.63)%,P=95%。样品均匀性引起的重复测量不确定度分量为最大,沥水时间误差导致的不确定度分量次之。

According to the common rules for measuring uncertainty,the uncertainty of measuring the content of solid things in fruit and vegetable cans is evaluated.Measuring results and results of evaluating uncertainty are (60.79±0.63)%,P=95%.The branch quantity of remeasuring uncertainty caused by the evenness of samples is maximum and the branch quantity of uncertainty caused by the error of watertogging time is less.
