摘要
通过对金属材料抗拉强度试验,对在测量过程中由重复测量、试件直径偏差等因素所引起的钢材试件抗拉强度测量不确定度进行了分析评定,为准确分析不确定度来源提供了依据。
Through the tensile strength test of metallic materials.The paper undertakes the analysis and evaluation of the measurement uncertainty of the steel specimen caused by the repeated measurement and the specimen diameter deviation in the measurement process,and provides the reference for the resource of accurate analysis of the uncertainty.
