| Abstract: | Describing the analysis method and mathematics model of measurement system repeatability and reproducibility （GR＆R）, residual analysis is used to test assumptions such as the model＇ s normality and homogeneity of variance. The measurement system analysis of a body＇ s quality is taken as an example, according the result of the GR＆R analysis and residual analysis to determine the main reason of measurement system error and find the direction and method to improve the measurement system, and gives suggestions for improvement. |
