此外，还可以观察到巨坑或地面冲击波的现象，这些现象将在第六章中加以叙述。
In addition, cratering and ground shock phenomena are observed, as will be described in Chapter VI.
强度最大处位于飞机正下方，随着离飞行路线的横向距离的增大强度不断减小，直到因为冲击波在地面的折射而消失。
Maximum intensity is directly beneath the aircraft, and decreases as the lateral distance from the flight path increases until it ceases to exist because the shock waves refract away from the ground.
一般，飞机飞得越高，冲击波(到达地面)所需要移动的距离就越大，使得音爆强度减弱。
Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
