It was the idea of supporting a craft on a 'pad', or cushion, of low-pressure air, ringed with a curtain of higher pressure air.

用一个低压空气或软垫来支撑船体，软垫周围用高压空气环绕。

This polka dot balloon is filled with high pressure air particles and when popped, all these particles rush out and hit the adjacent air particles.

这个圆点气球充满了高压空气颗粒， 当爆裂时，所有这些颗粒都会冲出并撞击相邻的空气颗粒。
