| Abstract: | How to exactly evaluate and express the uncertainty in measurement is a very important problem. In this paper ,the meaning of uncertainty is put forward ,and the relevant concepts are introduced. According to the measurement model for practical work, the various specific methods for Type A and Type B evaluation of standard uncertainties and the expression for expanded uncertainty are given. The procedure for evaluating and expressing uncertainty is summarized, and practical examples are given. |
