Sound, you'll recall, is a wave: a 'longitudinal' wave.
如前所述，声音是一种波： 纵波。
Physics
In the case of a longitudinal wave, the back-and-forth motion is more of a compression-and-expansion.
在纵波的情况下，来回运动更像是压缩和膨胀。
Physics
But there are also longitudinal waves, where the oscillations happen in the same direction as the wave is moving.
但是也有纵波，其中振荡发生在与波移动的方向相同的方向上。
Crash Course 综合篇
But sound is the other kind of wave: it’s a longitudinal wave, meaning that the wave’s back-and-forth motion happens in the same direction in which the wave travels.
但声音是另一种波：它是一种纵波，这意味着波的来回运动发生在与波传播相同的方向上。

Longitudinal waves, also known as "l waves", are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium. The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation. Some transverse waves are mechanical, meaning that the wave needs a medium to travel through. Transverse mechanical waves are also called "t-waves" or "shear waves".
