doppler meaning in English

多普勒效应

The doppler frequency is a function of the two scattering directions .
多普勒频率是两个散射方向的函数。
The doppler frequency can be obtained as a heterodyne or beat effect .
由于外差或频差效应，能够得到多普勒频率。
This is found by observing the doppler shift in the frequency of the radio signals broadcast from the satellite .
这是通过观测卫星所发射的无线电信号频率中多普勒偏移来确定的。
Moreover, since the atoms are in random thermal motion the frequency spectrum will be altered by the doppler effect .
而且，由于原子是在作无规则热运动，多普勒效应也会使频谱发生改变。
