摘要
依据室温拉伸试验新标准,分析了拉伸试样、试验要求等方面的变化;分析了新标准中抗拉强度、屈服强度 的变化及工程应用注意事项;对伸长和廷伸进行了区分,比较了新旧标准一些概念的变化.希望对教学、科研等使 用新国标有所帮助.
According to the new standard of room temperature tensile testing, the change of tensile speci-mens' the requirements and other aspects are analyzed. The changes of tensile strength and yield strength are analyzed and engineering application is discussed. Elongation and extension are distinguished' and some concepts of the new and old standards are compared. I hope it helpful to the use of the new national standard for the teaching' scientific research.
