The main steam, having been condensed in the condenser, is now in a liquid state at a very low pressure and approximately saturation temperature. 在凝汽器中冷却的主蒸汽现正处于压力非常低和大约饱和温度的液体状态。
' This work shows that some reactions are possible under very low pressure and this is a very exciting possibility, 'comments Hutchings. 这项研究证明在低压下,一些反应是可以进行的。这是一种令人兴奋地可能。
A radiometer consists of four vanes free to rotate about a pivot inside a bulb containing air at very low pressure. 辐射计是在充有很低压强气体的球泡内,装置能绕支点自由旋转的四个叶片。
Under very low pressure, even if subcooling at the exit of heated test section is relatively high, the flashing in riser still appears due to gradual energy accumulation by strong thermodynamic non-equilibrium process. 在低压下,即使加热段出口过冷度相当大,也会因强烈的热力学不平衡过程导致上升段中能量的积累。
Thought water is a good refrigerant, it is difficult to be used directly in a common compression refrigeration system due to its very low pressure and vapor density at the evaporation temperature. 由于水的蒸发压力低、比容大使得水作为制冷剂直接用于压缩式制冷系统还有很大的困难。
