When people do this we call it ‘procrastinating’ but when cats do it we call it ‘ displacement behavior‘
人若如此被称为“拖延”，但猫若如此就被叫做……“换位行为”。
The displacement activity, the grooming, the straightening of its feathers, seems to be an irrelevant behavior.
替换活动，如梳理、拉直羽毛，似乎都是无关的行为。
To develop the RAINBOW piezoelectric actuator with ultra-high displacement, the reduction behavior of PLZT piezoelectric ceramics was researched by experiments.
为研制具有超大位移的RAINBOW压电驱动器，实验研究了制备该器件的PLZT压电陶瓷的高温还原行为。
