Spectrum Doppler showed increased blood flow velocity in the proximal stenosis, and distal flow reduction.

频谱多普勒显示狭窄近段血流速度增高，远段流速减低。

Objective 1 To evaluate the character of color Doppler and frequency spectrum Doppler of cerebral artery stenosis by examining the patients who were suspected with cerebrovascular disease with TCCS.

目的1对怀疑有脑血管疾病的患者进行经颅彩色多普勒超声（TCCS）检查，探讨颅内动脉狭窄的彩色多普勒及频谱多普勒特征。

If you have a binary system whereby both stars are visible so you get the spectrum of both stars, then you see the Doppler shift of both stars in the spectrum.

若存在一个双星系统，两颗恒星均看不见，你能得到双星的光谱，然后在光谱中看到，双星的多普勒顿移。

This is a reddening of a galaxy's spectrum caused by the Doppler effect (the effect that causes a police-car siren to drop in pitch as the car drives away).

ECONOMIST: Astronomy

The spectrum of the light reflected from the planet is Doppler-shifted because the planet, like the ambulance, is moving.
