文章介绍了金属材料室温拉伸试验测量结果不确定度的方法，内容包括抗拉强度、下屈服强度、规定非比例延伸强度、断后伸长率和断面收缩率等性能指标。
Evaluation of uncertainty of measurement in testing for materials at ambient temperature has been discussed, including tensile strength; lower yield strength; proof strength, nonproportional extension; percentage elongation after fracture and percentage reduction of area.
