【摘要】 利用Newton-Raphson法拟合了气-液平衡计算中最困难的二元含水体系(水-乙醇体系)气液平衡组成的Wilson方程参数。结果表明,该方法简单,计算精度高,有理论和实际意义。在全部浓度范围内与实验值比较,结果说明,Wilson方程能很好地应用于该体系,计算结果令人满意。更多还原

【Abstract】 This paper optimizes the potential parameters of Wilson equation in water- ethanol system via Newton-Raphson method. The results show that this method was simple, high accurate and satisfied. And Wilson equation may apply to water-ethanol system in all the concentration range compared with the experiment data.更多还原
