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.
