Analytical solutions were obtained, and the formulae for resonance frequency, velocity distribution, amplitude ratio and node location derived.
我们获得了解析解，然后给出了共振频率、速度分布、振幅比和节点位置公式。

The harm of the secondary resonance could be improved by the measures such as using the acceleration detector core body, increasing the damp of velocity detector core body and so on.
