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. 其次運用該文推導的阻尼比計算公式提取各振蕩模態分量阻尼比，從而實現低頻振蕩模態參數的有效提取。
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. 用雙色激光同時照射兩個離子，振蕩模處於虛激髮狀態，所以系統對熱場不敏感。
The resonant frequency of a quartz crystal is generally determined by the size of the plate combined with the mode in which it vibrates. 石英晶體的諧振頻率通常是由組合振蕩模式之振動片尺寸來決定的。
