phase velocity

基本解釋

And the phase velocity of fast wave will decrease exponentially with frequency.
快縱波的相速度隨頻率的增大以指數(shù)形式減小。
With an increase of organic phase velocity, the recovery of solute decreased, while maximum mass flux may exist.
有機(jī)相流速的增大，將使萃取率下降，傳質(zhì)通量則可能存在極大值；
Using this technique, we invert the phase velocity of Raleigh wave in the Tibetan Plateau, revealing the horizontal variation of S wave velocity structure near the center of the Tibetan Plateau.

the speed at which the phase of a wave is propagated, the product of the frequency times the wavelength. This is the quantity that is determined by methods using interference. In a dispersive medium it differs from the group speed (Also called wave speed, wave velocity)
