The reduced pressure distillation experiment on the liquid paraffin was done and the Engler distillation curve was obtained.

进行了石蜡油的减压蒸馏实验，得到了恩氏蒸馏曲线。

So then, in a practical way, it's possible to walk quite far along the distillation, the coexistence curve, and distill to really a high degree of purification.

如此反复，实际过程中，可以沿着，共存曲线蒸馏很久，然后提纯到一个很高的纯度。

This model austerely simulating dynamic action of vacuum distillation unit, and the dynamic curve of vacuum's sidetrack from feed-in to static state.

该模型严格地模拟了减压精馏塔的动态行为，模拟了稳态下进料发生变化时减压精馏塔中各塔板上液相浓度变化的曲线。
