关于弯曲液面蒸气压的两点讨论

Discussion on two aspects of vapor pressure at curved gas-liquid interface

以外压对蒸气压的影响及开尔文方程为理论依据,讨论了外压对弯曲液面蒸气压的影响,其结果与外压对平液面蒸气压的影响相同。讨论了液体内部气泡的蒸气压,给出了气泡内蒸气压的计算公式,并对现实中的实例进行了计算说明。

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.
