The gas-liquid dissolved state is shown as the dissolved state of liquids after the polar reaction or other chemical reactions of gas solute and liquid solvent water. Before and after dissolution, the gas solute is subjected to a process of liquefaction and exo- therm. The gas-liquid mixed state is shown as the mixed state of gas and liquid after the gas solute and liquid solvent (water) have no polar reaction or hydration reaction as well as dissociation and association. It is resulted from the uniform diffusion of gas solute into the liquid solvent, that is, the gas solute in the aqueous solution remains a special “gaseous state” in terms of the kinetic energy of gas molecules. As the temperature does not reach the liquefaction point, gas solute does not go through a liquefaction process then. The solubility of gas-liquid dissolved state is generally greater than 1, while the solubility of gas-liquid mixed state is generally less than 1. The gas-liquid dissolved s
