查询词典 chromophoric

Generally, its difficult to determin VPA in serum with HPLC because VPA lacks nitrogen and a ring moiety and therefore has no chromophoric characteristics.

丙戊酸缺乏氮和共轭环，因此紫外吸收弱，一般HPLC法难以实现。

The feature Chromophoric dissolved organic matter and its source in Meiliang bay and Da Taihu lake in Taihu Lake are analysed based on every 2 time′s samplings in summer with algal bloom and winter.

基于2004年夏季水华暴发期和冬季在梅梁湾及大太湖各2次采样，分析了夏季、冬季CDOM的特征及其可能的来源，发现夏季CDOM吸收系数、叶绿素a浓度均明显高于冬季，DOC浓度、CDOM吸收系数a(355)的变化范围分别为5.17～12.42 mg/L、2.57～6.77 m-1，最大值均出现在冬季(12月15日)的直湖港入湖口。

A series of organic reversible thermochromic materials are prepared using bromocresolpurple as chromophoric reagent,aromatic compound with hydroxyl(hydroquinone,bisphenol A,1-naphthol)as delomorphic rea- gent and hexadecanol as solvent.

以溴甲酚紫为发色剂，含羟基的芳香族化合物(对苯二酚、双酚A和1-萘酚)为显色剂，十六醇为溶荆制备了有机可逆热变色材料。

Considering the low morphological stability of dye-doped polymer thin film and based on the above multi-chromophoric organic small molecules, six novel copolymers have been synthesized by the co-polymerization, in which there are three functions: 1, 8-naphthalimide as emitting moiety, oxadiazole as electron transporting moiety, and N-vinyl carbazole as hole transporting moiety.

考虑到有机小分子掺杂到聚合物膜中低的形态稳定性，我们在上面多发色团有机小分子研究的基础上，通过自由基引发共聚合成了六个新型的共聚物。在该类共聚物的侧链上含有三个功能团：1，8-萘酰亚胺单元、噁二唑单元和N-乙烯基咔唑单元。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
