The base of a sculpture can be fitted with an isolator that protects the piece from shaking if there is an earthquake. 雕塑的底座可以安装一个隔离器，在发生地震时保护雕塑不会摇晃。

You can mount a vibration isolator on the legs of your bed to dampen the vibrations caused by machinery in the building.

a device used, for example in a laboratory (= a place where scientific experiments are done), to keep a process separate from the environment around it

When working with mice in an isolator they may be picked up using a pair of large forceps with rubber covers on their tips. 在隔离器中处理小鼠时，可以使用一对顶端有橡胶套的大镊子夹起小鼠。
