A compression wave in decelerating flow steepens. 壓縮波在減速流中變陡。
So the compression waves pile up in front of the wingsfuselage, or body, of the plane. 這樣，壓縮波就堆積在機翼和機身的前面。
Two ignition methods are investigated to reduce pressure wave in large caliber gun propelling charge with high loading density. 研究了兩種能降低某大口徑火炮高裝填密度發射裝葯的膛內壓力波的點傳火方案。
Meanwhile, the spectrum is also related to the shock wave velocity. 光譜的結構特徵也依賴於激波的速度。
A new shock wave reactor for carrying out gas phase pyrolysis has many advantages. 新型的激波反應器可用於氣相熱解反應，具有許多優點。
