摘　　要：介绍了GB/T 228.1-2010标准的各项变更和新增内容。将新旧标准进行对比,针对原始横截面积、原始标距、应变速率控制、上下屈服点的控制以及试验结果数值修约等各项变更和新增内容进行应用实例说明。指出了标准实施过程中应用问题的解决方案,有利于试验人员准确的解读并更好的实施新标准。The changes and additions of GB/T 228.1--2010 were introduced. The new standard was compared with the older one. The changes and additions were illustrated by experiment, such as riginal cross sectional area, origi- nal gauge length, strain rate control, control of upper and lower yield point and test results of numerical repair. The solution of problem were referred for testers to use the new standard.
