This paper proposes a novel method to obtain the "partial pressures” of the water vapor and dry air in humid air. The results obtained by the proposed method are quite different from that obtained by Dalton's partial pressure law. The fundamental behaviors of water vapor and dry air are studied in depth in wide pressure and temperature ranges. Semi-permeable membrane models are proposed and applied for both saturated and unsaturated humid air. "Improvement factors” are developed to quantitatively describe the magnitude of the interaction between dissimilar molecules. One discovery is that the "partial pressure” of the water vapor in saturated humid air equals P s, rather than (f·P s) which was formerly believed. The other is that the interaction between dissimilar molecules may be omitted when temperature is above "cutting-off temperature” for unsaturated humid air. This paper satisfactorily answers the quest of "partial pressures” in humid air from a new perspective.
