  1. In the two - photon resonance case, part of the input pulse energy is transformed into higher and lower frequency components through amplified spontaneous emission and four - wave mixing, and the medium shows strong optical power limiting effect

    在雙光子共振情況下，即入射脈沖頻率等於1 、 3能級之間的共振頻率的一半，由於介質中放大的自發輻射和四波混頻的作用，部分入射脈沖能量轉化為高頻和低頻電場成分的能量，分子介質表現出了很強的光功率限幅特性。
  2. So the pipe system sends out noise because of resonance. especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe, so the 250hz is a dangerous frequency to the pipe system. there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern

    特別是激勵頻率為250hz的頻率分量恰好與管道系統的固有頻率相接近，其引起的管道振動對噪聲的貢獻最突出，同時也與水泵房房腔的固有頻率相接近，從而引起房腔共鳴發聲，使噪聲進一步被放大，以至於噪聲最大處高達105db （ a ） 。
  3. The formulas of three kinds of loaded ultrasonic transformers are presented ; then, the graphs of resonance frequency and the amplitude magnification coefficient, following the change of load, are charted by the programs of matlab

    得到了三類常用變幅桿頻率方程和放大系數的表達式；並通過matlab編程，分別繪制了三類變幅桿共振頻率及放大系數隨負載變化的曲線圖。
  4. Detecting a soft trouble of philips mri rf amplifier
