The experimental result also shows that the nitrogen element on the surface of contact black surface may be mainly in forms of amino group and nitro group.

此外，实验分析了接触法炭黑表面氮元素的组成，结果表明主要是以氨基和硝基的形式存在。

Nitro compound: Any of a class of chemical compounds in which the nitro group (-no2) forms part of the molecular structure.

硝基化合物：分子结构中含有硝基(- NO2)的任何一类化合物。

Donors such as amine and phenolic groups, when positioned ortho to a nitro group, are always involved in intramolecular hydrogen bonding.

在硝基邻位上存在的氢键给体如胺基，酚基时，总与硝基形成分子内氢键。

Nitramines are substances which contain a nitro group bonded to nitrogen.

含有与氮原子相连的硝基的物质称为硝胺。

Moreover, catalytic hydrogenation can be used to the reduction of a variety of organic compounds, such as nitro, carbonyl, amino, aromatic and heteroaromatic compound, hydroxy group and carboxy group.

此外，它除了还原双键以外可以用来还原各种不同的有机化合物，如：硝基、羰基、氨基、芳香族及杂环化合物、羟基、羧基。

Because of nitro group, the fluorescence intensity of other pyrazolines has decreased, the UV, fluorescence spectra also have red shift.

基本上得到了我们预想的结果其它的几种薄膜由于硝基的引入，荧光强度减弱，而且紫外和荧光光谱有明显的红移现象。
