Testing methods for chemical resistance of plastics under constant tensile deformation 在恒定拉伸变形下塑料耐化学作用的试验方法
It ' s square copper signet with anamorphic inscriptions due to pics . it ' s only for playing 是方铜印,印文照得有点拉伸变形了,印也不到代,闲玩的。
Tensile test and cyclic strain test of copper single crystal were performed . there are three stages in the plastic deformation 观测到铜单晶在拉伸变形过程中的三个阶段,得到了循环应力应变曲线。
Then , it presents two methods of the pull - out tests to the different stress - strain characteristics for the geofabric and the geogrid 其次,针对土工布、土工格栅的不同拉伸变形性状提出了两种拉拔试验方法,经试验证明可行。
16 not only will the tattoo stretch during pregnancy there is no guarantee that the tattoo will go back to its original shape after the birth of your baby 腹部纹身不止在怀孕时会拉伸变形? ?你的孩子出生后它也不能保证可以恢复原样。
