Unsteady separated flow , produced during the gate - opening period in the reverse radial gate tunnel of a high - lift shiplock , is characterized by negative pressure and high velocity as well as their intense fluctuations in space and time and could easily result in various harmful phenomena such as cavitation , gate vibration and sonic boom , which have been observed and confirmed by prototype and physical model tests 高水頭船閘輸水反弧閥門開啟過程中,后廊道內發生急變分離流,負壓、高速水流以及壓力與流速的劇烈時空脈動變化容易誘發空化空蝕、門振和聲震等有害現象已被原型觀測和物理模型試驗研究證實。

Although the spacecraft created a sonic boom that could be heard along much of florida ' s eastern seaboard , witnesses on the ground could not see the orbiter until it was directly over the runway lights 雖然太空船在沖破音速時所制造的爆音可以被佛羅里達州東邊緣海的人聽到,但在地面上是無法看到的.目擊者要直至等太空船直接在跑道燈上才能看見這首剛從軌道回來的太空船

If the burrow is in devon , that implies a cruising speed of 900 m . p . h . ? so the sonic boom would make them highly conspicuous even if they were invisible 如果陋居在德文郡,那意味著900英里每小時的巡航速度? ?因此即使他們是看不見的,音爆會使他們非常顯著!

A sonic boom is the loud crash and shaking that happens when a jet plane goes faster than the speed of sound 聲爆是當噴氣式飛機超音速行駛時產生的巨大碰撞和搖動聲。

From protection against enemies to social security to sonic booms , insurance has come a long way 從保證不受敵人侵犯,到社會安全,到聲爆,保險業走過了一條長長的路。

That was a sonic boom 剛才是音爆嗎
