基本解释

In many cases, a rectifying column with reflux is used to improve the performance of the batch still.
在許多情況下，用帶有廻流的精餾塔以改善間歇釜的分離性能。
The dynamic characteristic of concentration change on plates of batch rectification column in no reflux start up process and in no reflux period of pulse operation process have been calculated.
建立了間歇精餾無廻流操作過程的數學模型，採用四堦龍格庫塔法求解初值問題，計算無廻流開工過程及間歇精餾脈動操作過程中無廻流周期內各塔板濃度變化的動態特性。
Adding intermediate reflux and cooler and using packed column replaced plate column are suggested. The effect is evident in practice.
