For the pairs of these compounds, the chemical shifts of protons on amidenitrogen and the UV spectra arc helpful for assigning configuration.
对于成对的化合物，酰胺氮上质子的化学位移及紫外光谱亦有助于判断构型。

We also improved the conventional formol-H2SO4 titrimetric method, and applied it into the determinations of the contents of amidenitrogen and total nitrogen in urea nitrate metal complexes.
Of three nitrogen fertilizer types, the amide-form nitrogen source was better to the formation and accumulation of gliadin as well as its four fractions.
