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,如无填充材料的sa-403 焊接管件、sa-333焊制管及sa-334焊制换热管等, asme ii-d列出的应力未包含焊缝有效系数0.85,这样,仅体现出纵向许用拉应力。查看更多
