"Elastic deformation" 是 "弹性变形" 的英文翻译。
来源：弹性变形是指物体在受力作用后恢复原状的能力。这种能力是由物体内部的分子键所决定的。当物体受力时，分子键会发生变形，但在力消失后，物体会恢复原状。
例句：
"The steel bridge was designed to have a significant amount of elastic deformation to withstand strong winds and earthquakes."
"The rubber band is able to return to its original shape due to its elastic deformation properties."
例句翻译：
"钢桥是设计出来能承受强风和地震的巨大弹性变形的。"
"橡皮筋之所以能恢复原状，是因为它具有弹性变形性质。"
