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於磨料顆粒的衝擊速度。 - 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.
針對衝擊速度較低的情況，假設衝擊過程為小應變，並引入彈塑性增量本構關係，推導出衝擊過程的再生核質點法計算控制方程。
