丁胺

Chlorine atoms were selectively introduced into the chlorin ring based on different reactivity between vinyl group at 3-position and 20-meso position by electrophilic addition and electrophilic substitution using hydrogen peroxide/hydrochloric acid, N-chlorosuccinimide, hydrogen chloride (or concentrated hydrochloric acid) as chlorinating reagent.

In the pharmaceutical aisles, I found 61 varieties of untan oil and sunblock , and 80 different pain relievers —aspirin, acetaminophen, ibuprofen; 350 milligrams or 500 milligrams; caplets, capsules, and tablets; coated or uncoated.

在药品的过道上，我发现有61种不同的untan 油和防晒霜，还有80种止痛药——阿司匹林，乙醯胺基酚，异丁苯丙酸，还分350毫克和500毫克；还有囊片，胶囊，药片，其中还分有有包裹层和没有包裹层的。

The degrading rate of butachlor increases with the temperature going up.H+ and OH- were also known to catalyse...

Segmented polyester polyurethaneurea based n 4, 4'-disphenylmethane diisocyanate, ethylene diamine and polybutylene adipate elastomers and their deuterated polymers were studied by means of IR spectroscopy.

用红外光谱法对基於4，4'-二苯基甲烷二异氰酸酯、乙二胺和聚己二酸丁二醇酯的嵌段聚酯型聚脲氨酯弹性体及其氘化產物进行了研究。

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。
