| 1. | The entropy density is constant ahead of the shock .
冲击波前方的熵密度是恒定的。 |
| 2. | This type of behavior is not associated with underground shock .
在地下冲击波中，这种状况并不出现。 |
| 3. | The shock from the explosion crushed the rock to a radius of 130 feet .
爆炸形成的冲击波把130英尺半径内的岩石捣碎。 |
| 4. | A minor oscillation of the surface is experienced and a ground shock is produced .
地面受到轻度振动，并产生地下冲击波。 |
| 5. | Hence disturbances tend to grow, giving rise to the formation of a shock wave .
因此，扰动就趋于增强而引起冲击波的形成。 |
| 6. | The impulse is dependent upon the duration of the shock wave as well as its pressure .
脉冲的大小又取决于冲击波的延续时间及其压力。 |
| 7. | Tremors are caused by p and s shock waves and are also called preliminary tremors .
地动是由P冲击波和S冲击波引起的，也称为初期微震。 |
| 8. | It should be remarked immediately that this is proved here only for weak shock waves .
必须立即指出，这一点在此处只是针对弱冲击波加以证明。 |
| 9. | A complete study of the propagation of shock waves in elastic solids is presently lacking .
关于弹性固体中冲击波的传播，目前还缺少全面的研究。 |
| 10. | The massive blasts shook windows throughout the city, jolting sleeping residents awake .
大量的冲击波震动了整个城市的窗户，惊醒了睡梦中的居民。 |
