longitudinal wave [物] 纵波 ; P波 ; 纵向波
Longitudinal wave velocity 纵波声速 ; 纵波速度
wave-like longitudinal fin 波纹形翅片
Slant longitudinal wave 斜入射纵波
A little apart from the surf ace, the longitudinal wave beam may exist and propagate parallel to the surface, yet has to connect with its corresponding gliding irrotational waves.
离开固体表面稍远的区域,可以有平行于表面传播的纵波声束存在,但是需要与相应的滑行集散波相互衔接。
The longitudinal wave cannot exist near the surface of a solid, and those exist near it are gliding irrotational waves.
纵波不能在固体表面存在,在固体表面存在的是相应的滑行集散波。
It is the gliding irrotational wave pair, not the longitudinal wave beam itself that excites longitudinal wave in mud to generate signal.
激发出泥浆纵波而使接收器获得讯号的是滑行集散波,纵波声束并不直接激发泥浆纵波。
