EN13445-2中4.2.2几句话是什么意思啊? for operations such as drying and cleaning of pressure vessels, steels with specified low temperature properties but without elevated temperature 0,2 % proof strength values may however be used at elevated temperatures for drying and cleaning processes provided that the values of 0,2 % proof strength used in design calculations for elevated temperatures shall be obtained by multiplying the specified minimum yield strength values at 20 °c by the factor given in table 4.2-1. 朋友,先给你打一段我在google books上查阅到关于proof strength的释义,具体的你可以去参考( http:///books?id=nazwzk2xm-qc&pg=pa177&lpg=pa177&dq=proof+strength+values&source=web&ots=1b8am-shxi&sig=r6qatyepucxkz4p3xgmsg8twesc&hl=en&sa=x&oi=book_result&resnum=5& ct=result ) 已经给出低温属性但是没有给出温升时 0,2 %的认证强度值(proof strength)的钢可以在温升时进行干燥与清洁工作,前提是 通过将20摄氏度时 指定的 最大屈服强度值乘以表 4.2-1给出的系数得出 温升时 0,2 %的认证强度值。翻译的不是很好 最近在看钢的特性这部分 但也是皮毛 所以在这里献丑了 查看更多
企业标准的英文是enterprise standard吗? 抱歉,可能是我武断了,只是对这个译法"感觉不好" 刚google了一下company standard,看到米国做防务的洛马公司的一个文件里也用这个词,且明显指的是他们的一个内部标准,看来这个译法没问题 2.2 lockheed martin documents . the following operating document provides direction for the implementation of this company standard . lockheed martin electronics & missiles manufacturing process mp-86s48 control of electrostatic d ischarge 查看更多
