美国科学家找到一种新的检测方法,可以测定钢在承载时间内会产生过度疲劳以及何时可能导致断裂。美国伊利诺斯理工学院的物理学家汤姆斯·厄尔博和他的同事使用磁力,成功地测量出钢梁的疲劳强度。一个钢棒——即使是已被消过磁的——有一小束原子,其自旋
American scientists have found a new test method that can determine when steel is excessively fatigued during its loading time and when it may cause fractures. The physicist Thomas Ellbow and his colleagues at the Institute of Technology in Illinois used magnetic force to successfully measure the fatigue strength of steel beams. A steel rod - even if it has been degaussed - has a small beam of atoms and spins
