Thus it realized effective extraction of all parameters of LFO signals and put forward a new explanation of the mechanism of very low frequency oscillation. 其次运用该文推导的阻尼比计算公式提取各振荡模态分量阻尼比，从而实现低频振荡模态参数的有效提取。
In this dissertation, the accessional devices installed in the large dynamic elements for damping low frequency oscillations are named as the oscillation-damping device. 本文把在系统中各种大型动态元件中装设的用于抑制低频振荡的附加控制器统称为低频振荡抑制器。
