1·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。

2·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。

3·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。

4·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。

5·This paper presents the method of designing a acoustic sensor monitoring the shock wave and sound wave along with plasma produced in the process of interaction between short-pulse laser and teeth.

介绍了用于激光和牙齿作用后产生的等离子体监控的声学传感器的设计方法，可用于对激光作用过程的监控。

6·Hot firings show that the frequency of the oscillating shock is close to the acoustic frequency.

热试结果表明，振荡激波的频率与声频相近。

7·Product design is fashion with anti-shock, anti-theft, anti-rain, anti-dust, acoustic insulation and elegant appearance, fashion, it is widely used in commercial and public places.

产品设计新颖，具有防冲击，防盗、防雨水、隔尘、隔音效果、外观典雅、时尚，广泛用于商业，公共场所等地方使用。
