Then came that acceleration of locomotion. 后来，移动加快了速度。
This rotation amounts to a small acceleration of the laboratory . 这种转动相当于实验室有一个很小的加速度。
Modern science caused an acceleration of cultural change. 现代科学导致了文化变化速度的加快。
The CRAs and CRVs morphological features of Doppler frequency shift spectrums were recorded and analyzed with DRG Doppler retinal flowmeter(10 Mhz probe). 方法:采用 DRG眼用多普勒血流仪,对正常成年人男女各 24名双眼的 CRA、CRV多普勒频谱图象进行采集和形态分析。
However, in ionogram mode, though Digisonde works with many sounding frequencies, the resolution of Doppler shift is too low to detect ionospheric disturbances precisely. 而在频高图模式下
