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.
在液体受到束缚的系统里，液体到气体的大膨胀率能够迅速导致压力积累。
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.
如果暗能量的密度随时间降低，宇宙的膨胀速率将出现下降，如果其压力/密度比达到-1/3，那么宇宙的膨胀甚至会出现停滞。

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.
随着床层高度的增加，所需风压及功率增大，膨胀率有所降低，而床层密度的稳定性和起始流化气速几乎不变。
