axial velocity ratio的用法和样例：
例句
- The axial droplet velocity profile is nearly linear across the pipe section, and is different from the axial gas velocity profile.
液滴速度与气相速度分布不同，在垂直方向上液滴的轴向速度近乎呈线性分布。 - 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.
实验数据表明，螺旋翅片的导流作用使得迎风面的滞点处产生了轴向速度，这和光管有着本质的区别。
