查询词典 benzene

Although benzene is often represented with alternating single and double bonds between carbon atoms, the electron s in the bonds are shared or delocalized in such a way as to make all carbon-carbon bonds alike.

虽然往往把苯描绘成碳原子之间按单、双键交替排列，但事实上键中的电子是共享的，或者说是非定域的，其结果是使所有的碳原子都是等同的。

Using the enthalpy of formation of benzene and NO with the similar delocalizing electronic structure to correction, the calculated enthalpy of formation of TATB is acceptable compared with the experimental results.

结果表明，TATB分子中的苯环离域电子结构引起TATB生成焓计算的较大的系统偏差；利用具有相似离域电子结构的苯和NO的生成焓进行修正，计算得到的TATB生成热与实验结果符合较好。

Antibacterial deodorizes : The bamboo coal's charcoal structure is compact, the proportion is big, the holes are many, the mineral substance content is rich, therefore has the very strong adsorption resolution capability, to the air sulfide, the nitride, the methyl alcohol, the benzene, the phenol, the chloroform and so on organic pollutant or the harmful chemical substance, can display the outstanding absorption and disappear the smelly function.

六：抗菌除臭：竹炭的炭质结构非常致密、比重大、孔隙多、矿物质含量丰富，因此具有很强的吸附分解能力，对空气中的硫化物、氮化物、甲醇、苯、酚、三氯甲烷等有机污染物或有害化学物质，均能发挥优异的吸收和消臭功能。

His all people ladles an abusive language and the fact that swells is the fellow whom will go begging and ~ the benzene which translates

他的所有的人，钢包用一个粗言秽语和事实，即膨胀，是国人谁去乞求和苯转换

Because of its nonpoisonous, DMC can substitute phosgene , dimethyl sulfate or methylating used as methyl pharmaceutical to improve the security of production and reduce the environmental pollution; As the solvent, DMC can substitute fluorine lyons , methyl chloroform , trichloroethylene , benzene , dimethylbenzene, etc.. And it can be used as the paint dope, clean solvent. As gasoline additive, DMC can raise hard octane value and oxygen content and improve its antiknock possibility.

由于DMC无毒，可替代剧毒的光气、硫酸二甲酯等作为甲基化剂或羰基化剂使用，提高生产操作的安全性，降低环境污染；作为溶剂，DMC可替代氟里昂、三氯乙烷、三氯乙烯、苯、二甲苯等用于油漆涂料、清洁溶剂等；作为汽油添加剂，DMC可提高其辛烷值和含氧量，进而提高其抗爆性。

Among the 15 overfilling cases, nine of those were from gasoline tanks, two from crude oil tanks, two from oil products tanks, one from a phenol tank, one from a benzene tank.

在15 个过度充填的案件之中，九那些是从汽油坦克，二从原油坦克，二从石油产品坦克，一个从酚坦克，一个从苯坦克。

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。
