partial vapor pressure

基本解释

Flow and condensation of vapor with high partial pressure non-condensable gas in a separate heat pipe;
考察了不同的压力条件下不凝气对冷凝传热的影响。
Water activity is the ratio of the partial vapor pressure of water in equilibrium with a food to the partial saturation vapor pressure of water vapor in air at the same temperature.
水分活性是同温度下食品中水蒸气的分压力与纯水蒸汽压力之比。
Spherical pellet shape also makes a positive contribution during the drying process which functions due to the differential partial pressure of the water vapor between the pellets and the drying gas.
这种球形颗粒形状在加工过程中也起到积极作用，其功能体现水蒸气在球形颗粒和干气之间具有不均匀压力。
