查询词典 benzene

We again stress the idea that benzene represented as a resonance hybrid of two Kekule structures should not be imagined to be in one Kekule form one moment and in the other Kekule form the next oscillating between the two.

我们还强调以下概念：表现为两个 Kekule 结构的共振杂化体的苯，不应设想为在这一瞬间是一种 Kekule 式，下一瞬间又是另一 Kekule 式，这样的在二者间震惊。

In fact only by considering benzene to be a resonance hybrid comprising at least a pair of cyclohexatriene resonance structures can we come at all close to an accurate picture of the real molecule.

事实上，只有把苯看作是至少由一对环己三烯共振结构（叫做 Kekule 结构）组成的共振杂化体，我们才能全面接近真实分子的精确图像。

To alkyl benzene sulfonate as the main component of synthetic detergent, in the application performance and cost advantages than soap, the rapid development of a wide variety, a large number of production and life applications.

以烷基苯磺酸盐为主要组分的合成洗涤剂，在应用性能和成本方面都比肥皂优越，发展迅速，品种繁多，大量在生产和生活中应用。

Observing through SEM and TEM, we could found that the diameter of zeolite particle is during 10~20nm, the diameter of straight chain diatomite is between 8μm and 20μm, and the diameter of discoid diatomite is between 15μm and 20μm. From the diagram of TGA and DGA, we could draw the conclusion that the adsorption capacity of diatomite could be increased by heating method under appropriate temperature. The results of FTIR analysis show that there are several libration between 1510 cm~(-1) and 1529 cm~(-1), and this result can sufficiently prove the adsorption of benzene hydrocarbons.

4对材料进行了表征，通过SEM和TEM可以观察到分子筛粒径大小在10～20nm之间，直链结构的硅藻土直径约为8～20μm，盘状硅藻土圆盘直径约为15～50μm；经过TGA和DGA证实了，对硅藻土进行适当温度的活化可以提高硅藻土的吸附效果；经过IR分析，可以发现在1510～1529cm~(-1)之间出现了多个振动峰，这证明了分子筛对苯系物的吸附效果。

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。
