| Abstract: | he paper describes two methods to evaluate the combined uncertainty,which includes direct-method and indirect-method,as well as the methods on calculation of the standard uncertainty and expanded uncertainty. It is covered that its concepts,applications and examples.The six-key points described would be useful for the metrologists and testers while they evaluate the uncertainty. |
