| 1. | One example is provided by the sonic booms from airplanes .
飞机的声震就是一个例子。
|
| 2. | Pneumatic signals will travel only at sonic speeds .
气动信号的传输速度仅仅相当于音速。
|
| 3. | He found that the sonic surface was, in general, discontinuous .
他发现声速面通常是不连续的。
|
| 4. | Three additional comments on sonic sounder operation are considered pertinent .
关于回声仪的操作方面还有三点必须提及。
|
| 5. | Sonic oscillator provides a very efficient means of breaking cells or organelles .
超声振荡器为破碎细胞或细胞器提供一种很有效的手段。
|
| 6. | Sonic disruption over intervals up to ten minutes resulted in increasing amounts being liberated .
超过10分钟超声破坏导致了释放量的增加。
|
| 7. | A familiar example of resonance is the shattering of a glass by a particular sonic vibration .
大家熟悉的一个共振的例子就是玻璃窗被特殊的声响震碎。
|
| 8. | A few methods exploit other properties of flowing fluids, such as the propagation of various sonic waves .
还有几种方法能利用流体的其它性能，如各种不同的声波的传播。
|
| 9. | The holes themselves have a restricting or stabilizing effect because flow may become sonic .
因为这时流动可成为音速流动，所以这些小孔本身有一种节制作用或稳定化作用。
|
| 10. | This is, of course, the reason why a sonic boom hits us with all its fury from a supersonic aircraft but not from a subsonic one .
当然，这就是为什么音爆从超音速飞机上以它的全部力量向我们冲来，而音速飞机上则没有音爆传来。
