| 摘 要： | 萃取比是优化串级萃取工艺设计中的重要参数。本文导出了计算最优萃取比的精确方程。相同条件下，最优萃取比精确议程的计算结果误差小于现有的最优萃取比方程。当分离系数小于3时，计算最优萃到比既可用最优萃取比方程，也可用最优萃取比精确方程。当分离系数大于3时，计算采用最优萃取比精确方程更为合适。

| Abstract: | Extraction factor is one of the most important parameters in optimum design of countercurrent extraction technology. The precise equation for the optimized extractor factor has been deduced in this paper. The calculation error of the optimized extractor by the precise equation is lower than the error by the simple equation. If the separation factor is below three, the optimized extractor can be calculated by both of the simple equation and the precise equation. If the separation factor is over three, the precise equation is more suitable for calculating the optimized extraction factor. |
