查询词典 quinoid form

Under the influence of an external electric field defined by Sparkles, wecomparatively study the molecular structures and NLO responses of the push-pull thiophene quinoid molecules, push-pull furan quinoid molecules and push-pull pyrrole quinoid molecules. The results make known that the relative size ofthe molecular polarizability values for the three quinoid-type molecules dependson the selection of the donor-acceptor pairs.

比较研究了推-拉噻吩醌型分子、推-拉呋喃醌型分子以及推-拉吡咯醌型分子在点电荷外加电场作用下的分子结构和NLO响应，结果表明：这三种分子超极化率的相对大小取决于给体-受体对的选择。

This showed that the electron density of a quinoid ring increased. The peaks of the quaternary carbon atoms of the benzene rings, which were adjacent to the quinoid ring, also shifted to higher field. But the peaks of other C atoms shifted to lower field.

NMR结果表明苯胺低聚体掺杂后主链上的电荷重新分布，环上的H原子上的电子被C原子吸引，电荷密度降低，在〓 NMR中谱峰向低场移动。C原子的谱峰也相应发生变化，醌环上电荷密度增加，全部C原子的峰向高场移动，与醌环相邻苯环受其影响季碳峰移向高场，非季碳峰移向低场。

采用ASP 。NET 2003作为开发工具，数据库设计遵循第三范式，符合第二范式的条件，每个非关键字属性都仅由关键字决定，而且一个非关键字属性不能仅仅是对另一个非关键字属性的进一步描述(即一个非关键字属性值不依赖于另一个非关键字属性值)。，主要设计了物资编码表、稀土产品结构目录表、工作中心的基本情况表、工艺路线表、费用项目编码、产品成本总帐、产品成本明细帐、部门表、计量单位表、物料清单维护数型结构表、实际费用表、动能功率分摊比例表、工资费用分摊比例表、折旧费用分摊比例、维护费用分摊比例、化验费用分摊比例、主框架左菜单树表、材料价格表等数据表。

The results suggested that polys had smaller band gap relative to the their homopolymers, due to the coexistence of aromatic and quinoid form and the lower LUMO energy levels.

结果显示相对於其单聚合高分子，异芳香环次甲基共轭高分子有较小的能隙是因为aromatic 和 quinoid 型态能够在共轭鍊上共存，或者是因为拥有较低的LUMO能阶所导致。

During the bleaching process,there was no significant change of lignin structure unit.The carbonyl and quinoid structure had a close relati...

同时对不同纸浆在漂白过程中的变化进行了研究，对影响纸浆白度的因素进行了分析

The results indicate that the change of oxidation and doping condition affects the ratio of benzenoid to quinoid ring and the orientation order of the polyaniline chain, which are important factors to decide the conductivity of polyaniline.

这些结果表明：氧化与掺杂条件的变化影响到聚苯胺中苯环与醌环的相对比例、聚苯胺链的排列有序度，而这些也是影响聚苯胺电导率的重要因素。

The biosynthesis of coenzyme Q10 in microorganism has two pathways: the quinoid nucleus biosynthesis and the isoprenoid side chain biosynthesis.

辅酶Q10在微生物体内的合成分为芳香环的合成和异戊烯基侧链的合成。

CNTs didn＇t affect the doping degree of PANI, however stabilized the quinoid structure of PANI.

CNTs的加入提高了PANI的电性能，CNTs含量为12.82％时，PANI／CNTs复合材料比纯PANI的电导率高9.5倍。

CNTs didn't affect the doping degree of PANI,however stabilized the quinoid structure of PANI.

然而CNTs管径小，长径比大，易于聚集和缠结，PANI不熔难溶，难于用常规的熔融或溶液共混法制备PANI/CNTs复合材料。

The biosynthesis of the quinoid nucleus are the same in all coenzyme Qs. The biosynthesis of the isoprenoid side chain determine the kind of coenzyme Q.

芳香环的合成在所有的辅酶Q族物质中都是相同的，异戊烯基侧链的长度则决定了辅酶Q的种类，这里存在一个关键酶，即异戊烯焦磷酸合成酶。
