本文利用准高斯熵理论推导了一种在大温度范围内具有较高精度的汽液平衡压力的计算方法。我们得到的作为温度的函数的平衡压力的最终表达式可以被认为是克劳修斯-克拉珀龙方程的非常精确的近似解。该方法适用于水，甲醇和汞，并进行了比较，两个通常的近似克劳修斯-克拉珀龙方程。(C)1995年美国物理学会。
We derived a method to evaluate the liquid-vapor equilibrium pressure, with high accuracy over a large range of temperature, using the quasi-Gaussian entropy theory. The final expression that we obtain for the equilibrium pressure as a function of the temperature can be considered as a very accurate approximate solution of the Clausius-Clapeyron equation. The method was applied to water, methanol and mercury, and was compared to two usual approximations of the Clausius-Clapeyron equation. (C) 1995 American Institute of Physics.
