thus怎么理解? however for several other materials, e.g. sa-403 fittings welded without filler material ,sa-333 welded pipes and sa-334 welded tubes, the stresses tabulated in asme ii-d do not include the weld joint efficiency of 0,85 thus representing the allowable longitudinal tensile stresses. 然而,对于其它几种材料,如无填充材料焊接的sa-403 接头、sa-333焊管及sa-334焊管,除焊缝安全系数为0.85外, asme ii-d所列的应力 就 代表了允许轴向拉伸应力。查看更多
