摘要
模拟手工图解法求精馏理论塔板数的过程，用ＧＷＢＡＳＩＣ语言编写出计算机程序，在ＵＣＤＯＳ５０的支持下，采用全中文人机对话的形式键盘输入相对挥发度、塔釜残液浓度、塔顶馏出液浓度、料液浓度数据．通过计算获得并显示出精馏操作线方程、提馏操作线方程，非沸点进料时还显示出加料线方程，并获得梯级图各端点的坐标值．最后在中分辨率状态下，经过坐标变换后，直观地绘出梯级图．
Simulating the process of getting rectification theoretical tower plate numbers by handmade drawing, we programme computer procedures with GWBASIC language and input relative evaporativity, the concentration of residual liquid at the bottom, the concentration of distillated liquid at the top, and feed liquid by means of manmachine communication and with the help of UCDOS5.0. The calculation brings about the equation in rectification operation, in extraction operation and the equation in chargein done at the nonboiling point; it also brings about the coordinate values at the extreme points of the cascade graphs. The final cascade graphs can be brwan by means of charges of coordinates in the medium resolving power.
