考虑到吉布斯-迪昂方程和Redlich-Kwong状态方程（Redlich和Kwong，1949年）及其由de Santis等人（1974年）修改的方程对逸度系数的限制，霍洛威（1977年）对Redlich-Kwong方程的修改计算了气体混合物中分子种类的逸度系数，这是错误的。使用正确的方程修正后的计算结果与霍洛威的计算结果相比，与理想情况的偏差要小得多。
Consideration of constraints imposed on fugacity coefficients by the Gibbs-Duhem equation and those inherent in the Redlich-Kwong equation of state (Redlich and Kwong, 1949) and its modification by de Santis et al. (1974) indicates that Holloway's (1977) adaptation of the Redlich-Kwong equation for calculating fugacity coefficients of molecular species in gas mixtures is in error. Revised calculations using the correct equation lead to much smaller departures from ideality than those generated by Holloway.
