In the medical isotope reactor to separate and purify the medical isotope 99Mo and 131I, the reactive heat is constantly generated in the process of reaction, associated with the production of fission gas. In order to control the average temperature (usually≤80℃) of the reactor to prevent the sample from volatilizing, the cooling system of the reactor need to be designed carefully.

在使用医用同位素反应堆分离提纯医用同位素99Mo和131I时，由于反应过程中会不断产生热量并伴随裂变气产生，为了控制堆内平均温度(通常≤80℃)以使样品不致挥发，这就需要精心设计反应堆的冷却系统。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
