查询词典 electron

After the exposure, the retinas were examined with light and electron microscope. results: under light microscope, irregular nucleoplasm and unclear border of nucleus in the ganglion cell layer were found in the experimental groups of 2 h, 12 h and 24 h. these changes were also found in the inner nucleus layer. under the electron microscope, swollen mitochondria and vacuolized endoplasmic reticulums were found in all the layers of retina in the groups of 2 h, 12 h and 24 h, most obvious in the group of 24 h. in the group of 72 h, only lightly swollen mitochondria and dilated endoplasmic reticulums were found in the ganglion cell layer of retina.

结果： 光镜：实验组中2，12及24 h组均可见视网膜神经节细胞层内细胞核出现核质不均匀，核边界不清，内核层细胞核也有同样改变；电镜：实验组中2，12及24 h组视网膜各层均出现线粒体肿大，内质网空泡样变，以24 h组最为严重，72 h组仅见视网膜神经节细胞层出现轻度线粒体肿大，内质网扩张。

Electron transfer reaction between the radical cations of purine nucleotides and some aromatic amino acids was studied by use of pulse radiolytic techniques. Time-resolved spectroscopic evidence revealed that the one-electron-oxidized radicals of dAMP and dGMP can be efficiently repaired by tyrosine and tryptophan.

鉴于在DNA光敏损伤过程中主要生成嘌呤碱基阳离子自由基，利用脉冲辐解技术研究了嘌呤碱基阳离子自由基与部分芳香氨基酸的相互作用，获得了酪氨酸和色氨酸对单电子氧化的dAMP和dGMP经快速电子转移修复的瞬态吸收光谱证据。

Where may make mistake: This the electron is voting answering it is a few easier to let a thing become, but increased plan ticket difficulty however actually, the reason is an electron those who poll is comfortable degree mean partner to be able to poll for many times, bring cramped of more true and false voting result.

何处可能出错：电子投票本应让事情变得轻易一些，但实际上却提高了计票难度，原因是电子投票的宽松度意味着股东可以多次投票，带来更多真假难辨的投票结果。

In this paper, based on the tight-binding Su-Schrieffer-Heeger model and by using a nonadiabatic molecular dynamic method, we investigated some unclear problems of polymers in details, such as polaron dynamic properties in different systems, the inelastic scattering processes of oppositely charged polarons driven by an external electric field,and the influence of electron-electron interactions on the dynamics of a charge polaron in conjugated polymers.

本论文基于一维紧束缚的Su-Schrieffer-Heeger模型，采用非绝热的分子动力学的方法，针对高分子聚合物中一些尚未清楚的问题，如极化子在不同体系中的动力学性质、正负极化子的非弹性散射过程，以及电子-电子相互作用对极化子动力学性质的影响等问题进行了较详细的研究。

Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.

共轭聚合物具有不同于传统半导体的特性，它们是强电-声相互作用的准一维体系，其载流子不再是简单的电子和空穴，而是伴随晶格畸变的具有内部结构的复合粒子(自旋1/2的极化子、自旋为0的双极化子等)，这些载流子的输运、以及正负极化子对复合成激子的过程在很大程度上决定着聚合物的电致发光性质。
