摘要：

The growth of supercritical bubbles in a liquid solution with time was determined with allowance for solvent fugacity. It was shown that the presence of solvent vapors in supercritical bubbles caused by the solvent vent fugacity tends to increase the growth rate of supercritical bubbles. As a result, the "driving force" of the growth of supercritical bubbles is not the supersaturation of dissolved gas but the calculated larger parameter that takes into account the solvent fugacity. The condition of the steady-state regime of the absorption of gas molecules by the supercritical bubbles from solution with the movable bubble boundary was studied. The maximal volume fraction of all supercritical bubbles in solution was found. The condition of mechanical equilibrium between the supercritical bubbles and the solution was studied.
