摘要：In order to make die new model of gas solubility proposed by our previous work be applied to the dilute aqueous solutions, an internal pressure equation of. water is established from the intermolecular potential function. This equation can be used to describe the variation of internal pressure of water with the density over the wide range of temperature. The new model of gas solubility is tested by the experimental data of Henry's constant for gases in the water, and the consistency between the calculated and experimental values is satisfactory. In addition, the new model can also be used to explain the dimentions of Henry's constants and their rule of change with the temperature by solute-solvent and solvent-solvent interactions.
