Percentage ration of the actual vapour pressure in the air to the saturationvapour pressure with respect to water at the same temperature and pressure.
空气中的实际水气压与在相同温度和气压下的水面饱和水气压的百分比。
2
The model includes solid velocity, space grade of saturation with vapour density and space grade of porous pressure in concrete multiphase system.
考虑了混凝土多相系统中固体速度、饱和度乘蒸汽密度的空间梯度和孔隙压力空间梯度；
3
A vapour at saturation is in equilibrium with the bulk phase.
