利用Matlab7． 0 开发出图解计算精馏塔理论级数行的新方法． 该方法简单、准确、应用范围广，还可以通过改变输入参数，计算不同条件下精馏塔的理论级数，并能够可视化地输出理论级数的图解过程．-With Matlab7. Developed a new method for graphical calculation of ideal series. The method is simple, accurate, and a wide range of applications, and can also calculate the theoretical stages of distillation column under different conditions by varying the input parameters, and be able to output visual illustration of the theoretical stages.
