My hand drum to one's heart's content sings, happy song acoustic shock mountains and rivers.

我的手鼓纵情唱，欢乐的歌声震山河。

The mechanism of this instability is based on the cycle of acoustic waves between their corotation radius and the shock.

这种不稳定性的机制是基于声波在其同心圆半径和冲击之间的循环。

"Shock waves are acoustic waves that create pressure that can be focused," says Medispec's Gil Hakim, the company's director of new product development.

“冲击波是一种声波，它形成可以聚焦的压力，”Medispec公司的新产品开发总监吉尔哈姬姆说。

When a sound wave strikes the spheres at one end of the acoustic lens, the sound gets converted into a type of shock wave known as a solitary wave.

当把声波打击在声透镜一端的球体上时，声波就会转换成称为孤波的某种类型的冲击波。

The Nautilus meets withstands shock, vibration, salt, fog, drip, fungus, acoustic noise, and EMI.

鹦鹉螺还能抵抗撞击、振动、防盐防雾、防渗水并能经受噪声和电磁干扰的影响。
