In particular, they study the polarization properties of this kind of supernova in order to learn more about their asphericity, which holds important clues to the detailed physics that governs this terminal catastrophe in the life of such stars.

他们主攻的目标是研究这类超新星的极性，以了解其非球对称特征。在执掌这类恒星最终毁灭命运的物理机制中，这种非球对称性占据着重要的线索地位。

MARKET FORECAST: N, N-dimethylformamide is a basic chemical material and an excellent organic dissolvent.

The poison activity, stomach toxicity action and nonselective food refusal activity of extracts and fractions obtained by extracting the stem of Mirabilis jalapa L against the 4th instar larvae of Pieris rapae L, with 3 polarity solvents（petroleum ether, chloroform and ethanol）were determined by the methods of feeding, leaf-sandwich and leaf dish.

用饲喂法、叶片夹毒法、叶磲法测定了紫茉莉茎的3种极性溶剂提取物及萃取物对菜粉蝶幼虫的毒杀活性、胃毒作用、非选择性拒食活性。

These can be interpreted by the polar microregions theory proposed that the relaxor characteristics are caused by a gradual freezing process of polar microregions, which arises from the inhomogeneous crystal structure of this kind of material.

这可采用极性微区理论阐释，弛豫特性是由此类材料非均衡性产生的极性微区在逐渐冻结过程中引起的。关键词： K0.5Bi0.5TiO3；铁电结构相变；弛豫特性；溶胶-凝胶法

Most of polar polymers possess comparatively high values of relative permittivity, which means that both bonding and non-bonding electrons in the molecular structure of these polymers can be easily displaced by external electromagnetic force.

大多数极性聚合物具有相当高数值的相对电容率，其意味着这些聚合物的分子结构中之结合与非结合电子两者，可以轻易以外部电磁力加以排出。

The difference in solvent polarity environment between excited state intramolecular charge transfer and proton transfer states leads to a remarkable ESICT/ ESIPT coupled reaction. In polar, aprotic solvents, in contrast to a unique PT tautomer emission observed in 3-hydroxyflavone (3HF), dual emissions are resolved, consisting of ESICT and ESIPT bands.

不同於化合物3-hydroxyflavone只观察到异构物的质子转移萤光放射峰的结果，在极性、非质子酸溶剂里，我们会观察到3-hydroxyflavone衍合物有两个萤光放射峰，是分别经由ESICT与ESIPT两种不同路径个别的贡献。

Amino acids with nonpolar r groups are less soluble in aqueous solvents than amino acids with polar uncharged r groups.

带有极性非荷电的R基团的氨基酸能与水形成氢键，通常能溶于水溶液。

And a dead metal part that is exposed to contact by persons or that may be grounded, and uninsulated live parts and

在19.7和19.9注明的相对极性非绝缘带电零件之间的间隙，非绝缘带电零件与不带电金属件的

The fundamental concepts of micropolar fluid , couple stress fluid, fractional Maxwell fluid and smart fluid are described.

简要介绍微极性流体，应力偶流体，非整数阶Maxwell流体和智能流体的基本概念，通过简单的例子阐述它们与牛顿流体的本质差别，并介绍非牛顿流体在以上热点研究领域的若干进展。

This is because that the solvent polarity affects ICT process in two ways: on the one hand, the ICT state is better solvated in more polar solvent, which favors the ICT process; whereas on the other hand, the rates of non-radiative decay and intersystem crossing of the ICT state are increased, which unfavors the ICT process.

这是因为溶剂极性增大，一方面ICT态被更好地溶剂化，ICT过程活化能降低，有利于ICT过程的发生；另一方面ICT态非辐射跃迁和系间窜跃速率增大，导致ICT荧光猝灭。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
