1·The damping provided by the ER damper has the properties of both the Coulomb damping and the viscous damping.

电流变阻尼器提供的阻尼具有库仑阻尼和粘性阻尼的特点。

2·The result displays that the horizontal steady-sta te vibration is little affected by vertical Coulomb damping parametric excitations.

结果表明， 竖向阻尼参激对水平稳态振动的影响不大。
