In the aggregation process of polymer chains, when the time scale for the chain impenetration is far shorter than that for the chain collision, the polymer chains will aggregate to form spherical clusters.

对于高分子单链的聚集而言，当链贯穿的时间尺度远小于链碰撞的时间尺度时，链在聚集时就会相互缠结形成球形的聚集体。

In order to improve the solubility of the CNTs in solution without any structural damage, the surface-modified approach with noncovalent bond is considered. Anionic polyelectrolyte, poly(sodium 4-styrenesulfonate), used as modifier was applied to overcome the difficulty of CNT's dispersion into insoluble and infusible polymer matrix.

为了使奈米碳管在高分子基材中达到良好的分散性，又不会破坏其原始特性，本研究采用非共价键结表面改质的方式来进行奈米碳管之分散，研究中以阴离子型聚电解质，Poly(Sodium 4-Styrenesulfonate)，为奈米碳管分散剂。

Nanometer particulate electroporesis, cholesteric liquid crystal display, organic electroluminescent display, leuco dyes, inorganic electroluminescent display and conductive polymeric thin film transistor are used to develop the flexible electronic paper, which makes the applications of electronic paper such as electronic-book, smart card , inkless printing, electronic newspaper and so on come true.

纳米颗粒电泳、胆甾液晶、有机电致发光、隐色染料显示、无机电致发光等原理显示技术的开发，以及导电高分子薄膜晶体管的应用，使电子书、智能显示卡、无墨印刷、电子报纸等技术应用逐步成为现实。

Now the water as solvent adhesives, innoxious, nuisanceless, fire, but this is limited to ofmaize host materials can distribute a wide range of polymer resins, and polymer-coated plastic film, equipment, and so on are demanding, stability of less than ideal.

现已开发出以水为溶剂的粘合剂，其无毒、无公害、不燃烧，但这种粘合剂主体材料只限于能在水中分散的各类高分子树脂，而且对塑料薄膜、覆膜设备等均要求较高，粘合性能的稳定性不太理想。

In Chapter 5, photo-induced absorption is used to study the intersystem crossing from singlet to triplet states of two polyfluorenes after doped with Ir-complex. It is found that the triplet exciton lifetime of PFs is reduced by the dopants. But instead of decreasing, the population density of PF triplet exciton increases by almost one order of magnitude. The finding shows that the ISC rate can increase over 100 times due to the spin-orbital interaction with the Ir ions.

第五章以光诱发吸收光谱技术研究两种聚芴高分子掺杂绿光铱错合物后，聚芴的单重态到三重态的内部系统转换效率的改变；研究发现在掺杂后，聚芴的三重态生命期减短，但出乎意料的是其三重态的态密度并没有随之降低反而有一个数量级的增加，其原因为单重态到三重态的内部系统转换受铱错合物的影响效率增加了100倍。

By reacting isobutyraldehyde with diethyl oxalate using sodium methoxide as catalyst,3-methyl-2-oxobutanoic acid,sodium salt was prepared by one pot.

3-甲基-2-氧代丁酸钠是一种重要的酮酸类化合物，它在制药工业、高分子工业、食品工业、日化业等领域都有着广泛的用途。

The reaction proceeds through unstable intermediates such as the bipolar ion or peroxy radicals, which can isomerize or degrade, cause decomposition of macromolecules.

这一反应过程中，双极离子或过氧自由基等不稳定介质能引发异构或降解，从而导致高分子的分解。

The activated hydroxyl of the rare earth complex reacted with the -NCO of the of isophorone diisocyanate,and a new bonding-type rare earth polymer materials was prepared. We studied the optical property, thermodynamic properties of the materials were, and the results obtained show that the materials have high light transmittance and thermal stability as well as good fluorescence properties.

同时利用配合物的活性基团羟基与异佛尔酮－二异氰酸酯中的异氰酸根活性基团进行反应，制备出一种新型的键合型稀土高分子材料，并考察了该材料的光学性能、热力学性能等。

The results show that there existed at least two populations of lamellae in PEEK and other semi-crystalline polymers when isothermally crystallized.

结果发现PEEK及其他半结晶性高分子於等温结晶时便已形成两种以上之晶板分布。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
