homogeneous broadening meaning in Chinese

均匀加宽
均匀散频

In the case of homogeneous broadening only one mode can normally oscillate .
对于均匀加宽的情况，只有一个模能正常地振荡。
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
