impact velocity的用法和樣例：
例句
- The performance of abrasive waterjet depends on the impact velocity of abrasive.
磨料水射流的性能主要取決于磨料顆粒的沖擊速度。 - For a impact process with a normal impact velocity, the control equation for RKPM was deduced based on a small strain and incremental elasto-plastic constitutive law.
針對沖擊速度較低的情況，假設沖擊過(guò)程為小應變，并引入彈塑性增量本構關(guān)系，推導出沖擊過(guò)程的再生核質(zhì)點(diǎn)法計算控制方程。
