wave speed的用法和樣例：
例句
- By sweeping a laser along the pipe to change the local wave speed, physicists might be able to create a horizon.
將雷射沿著管路掃過，可以改變局部的波速，運用這種方式，物理學家也許可以創造出視界來。 - Furthermore, the non-dimensional propagation speed of an ISW declines and the dissipation of wave energy increases as the blockage parameter increases.
隨無因次障礙參數的增大，無因次波速減小，而內波的能量消散增大。
