中文摘要：

测量系统分析是质量改进活动中的一个重要问题，评价测量系统精确度的标准方法是量具的重复性和再现性（R＆R）研究，这种研究通常采用试验设计方法，而且对测量对象可以重复测量。然而在工业实践中，当遇到破坏性测量时，这种标准的R＆R研究方法是无法实施的。本文给出了破坏性测量中测量系统波动源分析的一种方法，首先分析了破坏性测量中进行量具R＆R研究的前提条件，进而给出了进行量具R＆R研究的随机效应模型和方差分析方法；最后通过应用Minitab．14软件，对工业实践中的一个应用实例进行了分析。

英文摘要：

A measurement system analysis is a vital issue for many quality improvement initiatives. The standard method for assessing a measurement system＇ s precision is a gauge repeatability and reproducibility （R＆R） study. Such a study involves an experiment in which each of a number of parts is measured multiple times. In industrial practice, however, applying the standard gauge R＆R set- up to destructive measurements is impossible, because parts can not be measured more than once. In this paper, the method for estimating the R＆R components in destruc- tive scenarios is discussed. First, the conditions for conducting an R＆R study in destructive measurement are explained. Then an experimental design model and the corresponding analysis approach for destructive gauge R＆R study are provided. And finally, a positive example from an industrial practice is studied by using Minitab 14.
