查询词典 moieties

The approaches taken to prepare NO releasing polymers are classified into three catogories:(1)doping discrete NO nonors within polymer matrix;(2)covalent attachment of NO resealing moieties on the filler particles of the polymer to provide NO releasing properties and then dispersion them into the polymer backbone;(3) covalent linkage of NO donors to polymer molecules.

制备可释放NO聚合物材料的方法主要有3种：（1）通过物理掺杂的方式将小分子的NO供体分散到聚合物材料中；（2）对聚合物材料的填料微粒进行化学改性，得到可释放NO的填料粒子，再将其填充到聚合物材料中；（3）通过共价键将可释放NO的基团连接到聚合物主链及侧链上。

CV indicated that the HOMO of DP1 is higher than that of DP2, which is resulted from the special effects of the pyrenes at C9 of the fluorene moieties, and the PL spectra of the two materials showed bright blue emission.

器件ITO／TCTA(8nm)／DP1 or DP2(30nm)／BCP(40nm)／Mg∶Ag都发出蓝光，但以DP1为发光材料的器件的性能远高于以DP2为发光材料的器件的性能，直流电压-电流曲线显示材料DP1有比DP2更高的载流子迁移率，芴9位的芘是造成这种结果的关键原因，并对这种原因进行了探讨。

Fluorescence studies reveal that the self-coiling tendency of organic molecular driven by HLI strongly depends on the length of the chain and the donor and acceptor moieties linked by methylene chains approach each other because of the self-coiling to induce the fluorescence quenching and form the intramolecular exciplex or radical-ion pairs.

结果表明，在一定极性的溶剂体系中，具有一定碳链长度的有机分子在疏水亲脂作用的驱动下能够产生自卷现象，从而使长链两端的电子给体和电子受体相互靠近，发生电子转移，造成有机分子的荧光淬灭。

The products obtained by co-heating carbon containing carbyne moieties and elemental sulfur, formed by base-induced carbonization of polyvinylidene chloride, have been characterized by 13C-NMR and Raman spectroscopies, XRD and SEM.

声为克服锂／硫电池的正极材料单质硫的导电性差、放电产物的部分溶解导致电池性能下降等问题，设计并制备了一种新型正极材料多硫化碳炔。

In the contrast, UVA damaged the deoxyribose and base pairs more seriously: some moieties were destroyed and some base pairs were modified.

UVA对脱氧核糖和碱基的损伤相对来说要严重些，一些基团结构被破坏，部分碱基对受到修饰。

A further step towards the prevention of inbreeding was taken by the Kamilaroi on the Darling River in New South Wales; the two original moieties are split up into four, and again each of these four sections is married en bloc to another.

进一步阻止近亲婚配的办法，可以在新南威尔士达令河流域的卡米拉罗依人中间看到，在那里，两个最初的级别分裂成四个，而这四个级别之中每一级别全体又都跟其它某一个一定的级别结婚。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
