在确定M M.Abbott三阶方程一般式最佳T_c等温线的基础上
提出了一个新的二参数三阶状态方程.在p_r=0—30、T_r=0.5—15之间
方程用于符合或近似符合普遍化压缩因子图表的流体
其误差一般均小于4%.同其它二参数三阶方程相比
本方程能获得更高的精度
同时也具备简便的特点.
On the basis of the generalized cubic equation of state proposed by Abbott
the author put forward a two parameter cubic equation of state which is universally suitable for fluids.Within the range of Pr = 0-30
and T = 0.5-15
when the new equation of state was tested on 400 data points
90.5% of the points has an error of less than 4%.Comparea to other two-parameter equations of state
the new equation has the advantage of accuracy and simplicity.
