axial velocity ratio的用法和樣例：
例句
- The axial droplet velocity profile is nearly linear across the pipe section, and is different from the axial gas velocity profile.
液滴速度與氣相速度分布不同，在垂直方向上液滴的軸向速度近乎呈線(xiàn)性分布。 - In addition, an axial velocity is observed at the windward stagnant point because of the guidance of the spiral fins, which is essentially distinct from bare tubes.
實(shí)驗數據表明，螺旋翅片的導流作用使得迎風(fēng)面的滯點(diǎn)處產(chǎn)生了軸向速度，這和光管有著(zhù)本質(zhì)的區別。
