5DP《钻杆规范》中6.8.3 Specimens The largest possible round-bar tensile specimens ,in accordance with the requirements of ISO 6892 or ASTM A370 ,0.2%offset method ,shall be taken from the longitudinal section location as shown in Figure B.3. 请高手们给指点下这句话的翻译,我们有两份翻译版本,这两份对0.2%offset翻译有争议,一个翻译成残余延伸一个翻译成非比例延伸,而这又正好是我们对引伸计的选择的关键,求教了!
