-
摘要: 对金属洛氏硬度测量中合成不确定度和扩展不确定度的分析与计算及在洛氏硬度测量中的实践应用进行了阐述。该方法对金属洛氏硬度的测量不确定度评定有一定的参考价值。Abstract: The analysis and calculation method of combined and expanded uncertainty and practical applications for metal Rockwell hardness measurement were explained. Then the evaluation method of uncertainty was also useful for other measuring cases.
