氮的

The process involved the preparation of vanadium carbide which can be prepared from V 2O 3 by vacuum carbon reduction and then being nitrified to vanadium nitride by nitrogen gas.

以V2 O3为原料，采用真空还原方法制备出碳化钒，生成的碳化钒直接进行渗氮制备出碳氮化钒。

However, the biomass of nitrifying biofilm could only increase slightly.

水力负荷对脱氮效果有很大的影响，低水力负荷能提高脱氮率。

The results showed that glucose was the best carbon source and organic N was much better than inorganic N. Czapek medium was the most appropriate for sporulating.

结果表明：葡萄糖是最好的碳源，有机氮远比无机氮好，Czapek培养基对孢子形成最适宜。

However, in recent years, many researches had showed that higher plants can take up organic nitrogen, particularly amino acid nitrogen.

然而，近年来越来越多的研究表明植物可以直接吸收有机态氮，特别是氨基酸态氮。

Protein is mainly made of amino acids, its nitrogen content is generally not more than 30%%, while nitrogen content as per melamine molecular formula amounts to 66％%.

蛋白质主要由氨基酸组成，含氮量一般不超过30%%，而三聚氰胺的分子式含氮量达到66％。

一氧化氮及一氧化氮合成酶作为血管舒缩调节剂，在脑缺血或脑缺血再灌注损伤中具有不同的作用，包括保护作用及毒性作用[1] 。

Compound 6 is a sheet of dimmers, in which two Mn ions are bridged by two EO azides and the dimers are linked by the single EE bridges into a sheet.

磁性分析表明配合物6的二维层内单EE叠氮桥和双EO叠氮桥分别传递反铁磁和铁磁相互作用，但整体表现反铁磁相互作用。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
