| Abstract: | Based on the theory of the effect of outer pressure on vapor pressure and Kelvin equation,the effect of outer pressure on the vapor pressure at a curved gas-liquid interface is discussed,which is consistent with that at a plane flat interface.In addition,the vapor pressure inside a gas bubble is discussed and a relevant equation is deduced for its calculation.To verify the validity of the equations,some actual examples are given in this paper. |

| Keywords: | vapor pressure plane gas-liquid interface curved gas-liquid interface outer pressure the vapor pressure inside a gas bubble |
