加速度减小 meaning in Chinese

loss of acceleration

The analysis results show that the palcement styles and the rotating angles of such a large scale deployable boom systems are functional importantly . the motions and damps of the boom systems also take importance . if motions become larger , the time for the booms to reach their spreaded states is shorter , and the impact velocities become larger , the impact accelerations become larger too
分析结果表明，对于大尺度的伸杆机构，其布置方式和展开角度对其展开运动有重要的影响；同时也研究了铰链处外力矩对展开运动的影响，随着该力矩的增大，伸杆到达锁定状态的时间减少，碰撞时的速度增加，由此产生较大的加速度；分析了伸杆弹性和阻尼对伸杆展开过程的影响，弹性增大碰撞加速度增大，阻尼增大加速度减小，因此可将铰链处外力矩和伸杆阻尼作为伸杆展开运动调节的手段。
