It can be widely applied to vibration control, especially applied in a low frequency and dense mode nonlinear system.
本发明可广泛用于振动被动控制，尤其适用于频率低、模态密集的非线性系统的振动控制。
In this thesis, we also discuss the mechanism of Flooding and Pruning in Dense-Mode multicast routing protocol and the process of switch from RPT to SPT in Sparse-Mode routing protocol.
并分别对密集模式组播路由协议的扩散和剪枝机制、稀疏模式组播路由协议中的RPT树到SPT树的切换过程进行了详细的探讨。
There are a lot of mode wave patterns near P-wave velocity line in 2-D spectrum, which have dense special distribution and large amplitude when the radial thickness of model well is thicker ;
当模型井的径向厚度较大时，二维谱中纵波速度线附近的模式波类型较多，空间分布较密集，幅度也较大；
