本文还讨论了弹性耦合和惯性耦合对共振频率的影响。
The effect of the elastic and inertia coupling on the resonance frequency is also discussed.
因为电子的惯性，它们将冲过平衡位置，并以特征频率围绕它们的平衡位置振荡。
Because of their inertia, the electrons will overshoot and oscillate around their equilibrium positions with a characteristic frequency known as the plasma frequency.
为使第二阶模态频率避开发动机一阶惯性力频率，文中对扶手架的质量、刚度进行局部修改，结果使手把振动有较大幅度的下降。
To separate these frequencies, we make a local modification to mass and stiffness of the handle and results in the vibration on the handle of walking tractor to reduce considerably.
