expansion pressure ratio

基本解釋

The large expansion ratio of liquid-to-gas can rapidly build pressure in systems where liquid can be trapped.
在液體受到束縛的系統(tǒng)里，液體到氣體的大膨脹率能夠迅速導(dǎo)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(xiàn)下降，如果其壓力/密度比達到-1/3，那么宇宙的膨脹甚至?xí)霈F(xiàn)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.
隨著床層高度的增加，所需風(fēng)壓及功率增大，膨脹率有所降低，而床層密度的穩(wěn)定性和起始流化氣速幾乎不變。
