研究表明:压缩变形是材料致密的主要因素,而扭转变形使变形均匀化。
The results show that the density is increased by compression deformation and the density uniformity is improved by torsion deformation.
伸缩缝由于铝合金温度变形较大,为使幕墙有足够的变形随动性,幕墙立柱需设置伸缩缝。
Expansion joints due to large aluminum alloy temperature deformation, to make the curtain wall has enough deformation servo, curtain wall pillar setting expansion joint.
而减径变形中的扭转变形不但使原始缺陷形成螺旋状,同时还进一步扩展了裂纹。
The distortion deformation during diameter reduction not only changes the primary defects (such as hair-line seams) into screwy form, but also enlarges the primary cracks.
It's only a slight variation that makes it a little bit more polite. A little bit less approaching.
这样轻微的变形可以使你的问题变得更为礼貌,也更为委婉。
