And when it is here again-- when the angle between f And so this phenomenon is called the Doppler effect.
当它再一次到这里-,当速度和你们之间的,撇又等于f，then，f，prime，equals，f，again。,这个现象被称为,多普勒效应。
Blind speed phenomenon due to Doppler frequency usually exists in moving target indication radar. This disadvantage affect is avoided through staggered pulse repetition frequency method.
动目标显示雷达中通常存在多普勒频率所引起的“盲速”现象，常采用参差脉冲重复频率的方法来克服这种不利影响。
We report the Doppler shift of Na spectroscopy changing with the slow wave factor in a slow wave microwave field the reason of the phenomenon is discussed.
报道了在慢波场中原子波谱多普勒频移随微波慢波系数的变化，并讨论产生这种现象的原因。
