但固结应力比与有效围压应力对阻尼比之影响则较不明显。

The influence of consolidation stress ratio on damping ratio is not distinct.

与油阻尼器被动控制相比，MR半主动控制可以有效地提高模态阻尼比，尤其在阻尼器位置距索端很近时仍有较好的控制效果。

However, the control efficiency of the MR semi-active control compared with that of the oil-dampers control is better, especially when the damper position is close to the end of the cable.
