地壳均衡回弹松弛时间 isostatic rebound relaxation time
不适当的成型压力的维持时间会破坏“压力回弹”作用，造成催化剂成型体的机械强度明显降低。
The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.
在该公式中，桩端土的静阻力可以直接从桩顶的加速度信号中获得的桩顶回弹和冲击力持续时间计算得到，并且计算结果和土阻尼无关。
In this method, the static resistance at pile toe can be calculated directly with the rebound at pile top and impulse duration from the acceleration signal at pile top.
