摘　　要：从R变化的角度解析理论塔板数的变化。进而探讨了Rm 的计算方法以判定R的抉择。同时研究了用这样大的R抽出氩馏分对空分主塔上下塔的影响及可行性。体验无氧氩新技术的理论准备的完整性。The paper analyzes the variation of number of theoretical plates viewing from the angle of R variation.Furthermore it makes an approach to the calculation method for R m in order to judge the selection of R.The influence of argon fraction drawn by using such a great reflux ratio of R on the performance of upper and lower columns of a rectification column and the feasibility are examined simultaneously.This represents integrity of theoretical preparations for oxygen/argon-free new technology.In addition,the corresponding changes in a pure argon column are demonstrated in the paper.
