partial vapor pressure

基本解释

Flow and condensation of vapor with high partial pressure non-condensable gas in a separate heat pipe;
考察了不同的壓力條件下不凝氣對冷凝傳熱的影響。
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.
水分活性是同溫度下食品中水蒸氣的分壓力與純水蒸汽壓力之比。
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.
這種球形顆粒形狀在加工過程中也起到積極作用，其功能躰現水蒸氣在球形顆粒和乾氣之間具有不均勻壓力。
