自从1873年货车·德瓦尔斯方程（货车·德瓦尔斯，1873）出现以来，许多作者提出了半经验关系的变体。最成功的修改之一是Redlich和Kwong（1949）所做的。从那时起，提出了许多修正的雷德利希-邝（RK）方程（Redlich和Dunlop，1963; Chueh和Prausnitz，1967; Wilson，1969; Zudkvitch和Joffe，1970;和其他人）。一些已经引入偏差函数来拟合纯物质PVT数据，而另一些已经改进了方程的汽液平衡（VLE）预测能力。对一些修正的RK方程的评论已经提出（Tsonopoulos和Prausnitz，1969）。Soave（1972）提出的RK方程的最新修正之一。Soave-Redlich-Kwong（SRK）方程由于其本身相对简单，与更为复杂的BWRS方程相比，已迅速为烃加工工业所接受
Ever since the appearance of the van der Waals equation in 1873 (van der Waals, 1873), many authors have proposed variations in the semiempirical relationship. One of the most successful modifications was that made byRedlich and Kwong (1949). Since that time, numerous modified Re-dlich-Kwong (RK) equations havebeen proposed (Redlich and Dunlop, 1963; Chueh and Prausnitz, 1967; Wilson, 1969; Zudkvitch and Joffe, 1970; and others). Some have introduced deviation functions to fit pure substance PVT data while others have improved the equation’s capability for vapor-liquid equilibrium (VLE) predictions. A review of some of the modified RK equations has been presented (Tsonopoulos and Prausnitz, 1969). One of the more recent modifications of the RK equation is that proposed by Soave (1972). The Soave-Redlich-Kwong (SRK) equation has rapidly gained acceptance by the hydrocarbon process-ing industry because of the relative simplicity of the equa-tion itself as compared with the more complicated BWRS
