| 1. | A pressure disturbance cannot drive the energy release profile uniformly to the anti-node region to result in a sustained longitudinal wave .
压力扰动不可能驱使能量释放分布图移至波腹区域以产生持续的纵向波。 |
| 2. | Unfortunately the shock conditions for accompanying longitudinal waves cannot be inferred at the outset without having detailed information about the shear wave .
很可惜，对伴随的纵波，冲击波条件却不能从一开始就在没有剪切波的详尽知识的情况下推测得出。 |

| 10. | " sound : mechanical disturbance that propagates as a longitudinal wave through a solid , liquid , or gas . a sound wave is generated by a vibrating object .
声音:以纵波形式藉由固体、液体或气体传播的物理扰动。声波是由振动的物体产生。 |
