跃迁频率 meaning in Chinese

transition frequency

Third , the whole absorption spectrum displays , in general , three pairs of absorption peaks and three pairs of gain peaks . due to the coherences between dressed states , these peaks are not exactly at the resonant resonance frequencies between dressed states , but in the vicinity of them
还有一个特征就是，吸收光谱在一般情况下会出现三对吸收峰和三对增益峰，在修饰态相干的作用下，这些峰并不是位于修饰态共振跃迁频率处，而是位于它们邻域附近。
With time - evolution - operator , it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system . the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level
引入时间演化算符，证明均匀增宽二能级体系在飞秒激光脉冲对作用下上能级激发态布居是周期性变化的，它以飞秒脉冲对之间的延时为时间轴，以该原子能级之间的跃迁频率为振荡频率
