In a definite scope, the impact time and contact area are linearly increased while the maximum acceleration and bruise volume reduced with the increment of thickness of cushion materials.
在一定范围内，随着缓冲材料厚度的增加，碰撞时间与接触面积线性增加，最大加速度与损伤体积相应减小。
2
The ellipse arc may depress the acceleration of supersonic flow in inlet area, decrease the strength of inlet shock wave.
椭圆形的前缘可减弱超音气流在前缘进口区的加速程度，降低进口弓形波的强度；
3
Motion prediction taking acceleration into account could effectively reduce the detection area and it consequently increases the tracking speed.
