研究团队中有一个人很擅长掰指关节,他每次将一个手指放入一个和电缆相连的试管中。
This wire was then slowly pulled until the joint in large knuckle in the middle of each finger popped.
然后电缆慢慢拉伸手指,直到每根手指中间的大关节发出响声。
After about six seconds pulling the cable, the two bones suddenly shot apart, creating a cavity, or bubble, within the fluid that bathes the inside of the joint.
电缆被拉大约6秒后,两块骨头突然分离,在关节内部的液体中形成一个空洞或者说是泡泡。
The cracking – which took less than a third of a second - occurred at the precise moment the bubble was formed, the journal PLOS ONE reports.
据PLOS ONE杂志报道,掰指关节的响声——响声持续时间不到三分之一秒——准确地与泡泡形成的时间吻合。
Lead author Professor Greg Kawchuk, from the University of Alberta, said: ‘We call it the “pull my finger study – and actually pulled someone’s finger and filmed what happens in the MRI.
这项研究的主要作者是来自亚伯达大学的Greg Kawchuk教授,他说:“我们称之为‘拉我的手指研究’(pull my finger study),实际上的确是拉伸某人的手指并用核磁共振观察发生了什么。
