摘要
针对Pitzer三参数通用关系式的局限性,本文提出了一个新的较简便的方程式。对19种物质140个状态点的检验表明,该方程式不仅应用范围较宽,而且精确度也比Pitzer三参数通用关系式,Die(?)erici方程,R-K方程和Berthelot方程高。
In view of the limitation of Pitzer three-parameter general relation, a new modified equation is derived. The results of verifying the equation with 19 kinds of substances including 140 state points show that the equation is suitable to more substances and state, and the predicted results are more accurate than those predicted by Pitzer three-parameter general relation, Dieteriei equation, R-K equation and Berthelot equation.
