涡电流隔离器自从20世纪90年代早期就开始得到使用，它是由长瓶状转鼓内的一个快速旋转磁力转子组成的，转鼓的旋转速度会较慢。

Eddy-current separators, in use since the early 1990s, consist of a rapidly revolving magnetic rotor inside a long, cylindrical drum that rotates at a slower speed.

当它们迅速摆腿，它们把展开的脚用力蹬水，如果保持了速度，那么所产生的小气涡能让它们不沉入水里。

As they rapidly churn their legs, they slap their splayed feet hard against the water, creating a tiny air pocket that keeps them from sinking, provided they maintain their speed.

因此，涡喷发动机更适合更高速度的飞行。

A turbojet, therefore, is more suitable at higher speed.
