摘要
用三次样条插值函数逼近汽－液平衡曲线方程，电算二元精馏的最小回流比。这种算法简单、快速、准确，适用于各种二元物系。
The vaPOur--liquid equilibrium data are fit to the vapour--liquid equilibrium curves equation with the cubic spline function,then the minimum reflex ratio in the binary rectification can be calcutated. This method iS sample,quiCk and accurate,and iS suitable for various binary systems and ranges of concentration.
