摘　　要：为了优化基于残奥定量的EBSD扫描面积参数,详细研究并讨论了置信区间和A类标准不确定度与扫描面积参数的关系。研究表明,综合考虑与扫描面积参数优化有关的扫描视场数(n≥6)、置信区间、A类标准不确定度、分析时间等主要影响因素可知,扫描总面积须达到65000μm^(2)。In order to optimize the EBSD scan area parameters based on the quantification of retained austenite,the relationship between the confidence interval and type A standard uncertainty and the scan area parameters were studied and discussed in detail.The research shows that according to comprehensively considering the main influencing factors such as the number of scanning fields(n≥6),confidence interval,type A standard uncertainty,and analysis time related to the optimization of scanning area parameters,the total scanning area must reach 65000μm^(2).
