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。
Based on the interaction between two ions and bichromatic radiation, the vibrational mode is only virtually excited so that the system is insensitive to the thermal field. 用双色激光同时照射两个离子，振荡模处于虚激发状态，所以系统对热场不敏感。
The resonant frequency of a quartz crystal is generally determined by the size of the plate combined with the mode in which it vibrates. 石英晶体的谐振频率通常是由组合振荡模式之振动片尺寸来决定的。
