吉氏函数积分证明麦克斯韦等面积法则

The Proof of Maxwell Construction Using G Function

本文阐述了由吉氏函数沿着可逆路径积分推导麦克斯韦等面积法则的过程。该证明过程表明,纯物质的饱和蒸气压计算中,麦克斯韦等面积法则等同于相平衡准则,这有助于加深学生对气液相平衡准则的理解。

The Maxwell construction was proven by the integral of G function along with a reversible path.The process showed Maxwell construction was equal to phase equilibrium criterion in the calculation of saturated vapor pressure of pure material.This is helpful for students to further understand the phase equilibrium criterion.
