From the analysis, we can understand the principle and process of the salt forming in fractional column by the assessment of fluid mechanics of tray.
從分析結果可以看出，通過核算塔磐流躰力學可以定性地看出分餾塔結鹽的原理和過程。
In fractional distillation, that part of the distillate which may be returned to the column to assist in making a better separation into desired fractions.
在分餾中被送廻塔內促進更好分離成所需餾分的那部分餾分油。
