测定

The experimental setup is designed to measure the change of dynamic holdup during the course of non-reflux period and the calculation value is consistent with the experimental results, which indicates that the downflow velocity of dynamic holdup becomes smaller with the decrease of dynamic holdup in the column during the course of non-reflux period.

本文设计了测定无回流过程中动持液量变化的实验装置，在与动态液相交换的全回流间歇精馏串联实验相同的条件下测定了无回流阶段的动持液量变化，模型计算值与实验值比较吻合，结果表明在无回流过程中随着精馏塔中动持液量越来越少，动持液向下流动速度也越来越小。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
