摘　　要：运用Excel快速获得双组分物系精馏塔的理论板数及每块塔板的温度、组成,既可用于理想物系也可用于相平衡方程未知的非理想物系。该方法具有简单易学、方便快捷和计算可靠的优点。By using Excel, it will be obtained quickly that the number of theoretic stage, temperature and concentration on each stage in binary mixture distillation column, not only for the binary ideal system but also for the binary nonideal system without vaporliquid equilibrium equation. This method with reliable result is simple to learn and master, convenient for application.
