| Abstract: | By repeating test for the non-protein nitrogen’s content of milk powder,calculating the test standard error,founding mathematical model of comment for process uncertainty,and then classifying and quantizing the uncertainty from systematical affection in the process of the test,it will more thoroughly evaluate each quantity of uncertainty,so coming up with a result. |
