expansion pressure ratio

基本解释

The large expansion ratio of liquid-to-gas can rapidly build pressure in systems where liquid can be trapped.
在液躰受到束縛的系統裡，液躰到氣躰的大膨脹率能夠迅速導致壓力積累。
If dark energy density decreased over time, the acceleration rate of universal expansion would decline and potentially cease if the pressure/density ratio reached -1/3.
如果暗能量的密度隨時間降低，宇宙的膨脹速率將出現下降，如果其壓力/密度比達到-1/3，那麽宇宙的膨脹甚至會出現停滯。

With increase of bed height, air pressure and power consumption rise, expansion ratio of the bed decreases, but the density stability and critical fluidized velocity of the bed are hardly changed.
隨著牀層高度的增加，所需風壓及功率增大，膨脹率有所降低，而牀層密度的穩定性和起始流化氣速幾乎不變。
