查询词典 donor

The result suggests that Al2O3 nanoparticle can stimulate donor function and thus result in a significant increase in conjugative plasmid dissemination in aquatic environments.

在一定条件下，纳米材料可促进质粒在液相中的接合转移，从而可能引发纳米材料的水环境安全问题。

The latest results about research on dye-sensitized solar cells are reviewed.So far,most of the organic dyes applied in DSSCs belong to typical D-π-A structures with both electron donorand electron acceptorlinked by aπ-conjugation bridge.According to this structure,the novel conjugated organic dyes that have N,N-dimethylanilinemoieties as the electron donor and a cyanoacetic acidmoiety as the electron acceptor were synthesized for DSSCs.

在第四章中首先概述了染料敏化太阳能电池的最新研究进展，并对其的结构和工作基本原理进行介绍，目前，有机染料分子大部分都是D-π-A结构，我们按照这样的结构设计和合成出六种新型米氏酮-氰基类有机染料分子，该类染料是由米氏酮衍生而来的，合成步骤短，工艺简单。

With cyclohexyl methyl dimethoxy silane as external donor,isotacticity of polymer turned to be more adjustable.

结果表明，使用环己基-甲基-二甲氧基硅烷，聚合物的等规度可调性好

Blood from a regular donor that takes pay for it is almost dependably pretty well washed up.

过去我并没有珍惜这些关键性的要求；或许这项恳求，能使我的朋友们去捐血。

Blood from a regular donor that takes pay for it is almost dependably pretty well washed up.

像是你、我朋友这种人能够提供好血，这是单从血来源来看。

Dialkylamine, which is an e-donor, was introduced at the C(4') or C(7) positions in 3HF resulting in similar ESICT/ESIPT dual emission. Even the net dipole moment, the orientation of which is affected by the CT effect, is expected different. Dialkylamine attached at both C(4') and C(7) positions in 3HF, of which the net dipole moment may be associated with the interplay between two charge-transfer systems, displayed different photo behaviors.

在3-hydroxyflavone的4'及7号位置分别修饰担任电子与体的二烷基胺类，在光谱上会观察到两种不同萤光波长，分别属於ESICT和ESIPT，但若同时修饰二烷基胺类，在不同极性溶剂下，会只有一个 ESIPT 的萤光。

The catalyst used diethyl 2,3—di—i—propylsuccinate as internal donor particles were also synthesized.

采用 2，3-二异丙基琥珀酸二乙酯为内给电子体合成了负载型聚丙烯催化剂。

The ultraviolet photosensitive initiating system is composed of 4,4"-bis(N,N"-dimethylamino) benzophenone, 2-chlorohexaarylbiimidazole and a hydrogen donor coinitiator n-dodecyl mercaptan.

用光敏剂4，4′-二(N，N′-二甲基-氨基)苯甲酮、引发剂邻氯代六芳基双咪唑和氢给体助引发剂十二烷基硫醇组成光敏引发体系。

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.

合成了以含硼基团为电子受体，以二甲胺基为电子给体，以苯乙烯基噻吩为共轭桥的新化合物2-[（4'-N，N-二甲胺基）苯乙烯基]-5-二米基硼-噻吩 trans-2-[(4'-N， N-dimethylamino) styryl]-5-dimesitylboryl-thiophene（简写为DMASBT，5）。X射线衍射方法测定其单晶结构表明，硼原子与π共轭桥之间的硼碳键相对于其它的硼碳键明显缩短，硼与π共轭桥之间存在除了σ键之外的p-π共轭作用。

Because diabetic neuropathy can be a painful condition that may be associated with nitric oxide, investigators tested a spray containing isosorbide dinitrate, a common NO donor used for heart patients, and found that it reduced overall neuropathic pain and burning with no effect on other symptoms.

由於糖尿病性神经病是一种可能与一氧化氮有关的疼痛疾病，因此研究人员检测一种含有isosorbide dinitrate的喷雾剂，此常见於心脏病患所需的NO产生，发现这种治疗可以缓解全身的神经性疼痛与灼烧感，但对其他症状却无效果。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。
