查询词典 imino nitrogen

IR spectra and UV spectra of the complexes are described. The results show that two phenolic oxygen and two imino nitrogen atoms in H2L coordinate to M ions.

通过对配合物的红外光谱和紫外光谱测定与归属，推测在三个过渡金属Schiff碱配合物中配体是通过酚羟基的氧原子和亚氨基的氮原子进行配位的。

If the nitrogen of these imino acids is involved in the peptide bond, the adjacent amino acid side chains are cis instead of showing the usual trans configuration, resulting in destabilization of an α- helix.

如果这些亚氨基酸中的氮进入肽链，那么邻近的氨基酸侧链是顺式的而不表现出通常的反式的构象，就导致了α-螺旋结构的不稳定。

The X-ray crystal structure analysis of the complexes shows that all lanthanidecomplexes exhibit a tripodal ligand coordination mode, with three imino nitrogenfrom benzimidazolyl and pyridyl group, and one amino nitrogen atoms as donors.The ligands show two kinds of configuration: the fan-like and the pincer-like. Bothintra- and intermolecular π-π interactions are found in these complexes.

晶体结果表明，在所有的稀土配合物中，三脚架配体均用三个支脚上的苯并咪唑、吡啶环氮原子及一个顶端的氮原子和稀土离子进行配位，表现出三脚架式配位方式，同时，三脚架配体有风扇形及钳子形两种空间配位构型，并形成了分子内及分子间的π-π堆积作用。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
