【Abstract】 By the uncertainty evaluation theory and method, In this paper, aim at the source and characteristic of ultrasonic thickness testing data, the relevance communicate was get out about random uncertainty more science and reasonable. the estimate method of ultrasonic thickness testing data was get out which can eliminated or partially decreased systematic uncertainty and unusual value, the quality of testing data was been elevated. Then, the analysis, the evaluated and the example of uncertainty were put up about ultrasonic thickness testing data for the personnel of inspect and testing.更多还原
