掺杂的

Chapter one: At the beginning of this chapter, we reviewed the history of manganite research. And then we laid an emphasis on the discussion of its physical properties-including crystalline structure, magnetic structure, electron structure and electromagnetic behavior, and related interactions in the system. After that we introduced some elementary properties of layered manganites.

第一章 首先简要回顾了超大磁电阻研究的发展历史，然后着重介绍了掺杂锰氧化合物的各种物性——晶体结构、磁结构、电子结构和电磁特性，及相关的各种相互作用，并对层状锰氧化物的基本性质作了简要介绍。

在本文中，我们研究了四价离子在锰位掺杂对锰氧化物材料性能的影响，并比较了上述两种理论的适用性和合理性；同时，我们还研究了A位空穴锰氧化物体系中MnO〓八面体的结构畸变，以及对磁学特性和电导行为的影响。

When the distance between microstructures is larger than 1μm, the influence of space charge is a negligible quantity, and the approximation of metal formula could be used.

研究了介观尺度下半导体表面空间电荷层对微结构间静电作用力的影响，并同宏观尺寸下采用的金属近似公式进行了比较，揭示了半导体表面空间电荷对静电作用力的影响同微结构间距离、材料掺杂浓度等因素的关系。

Far better it is to dare nighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows neither victory nor defeat.

冒险去从事伟大的事业，赢得光荣的胜利，即使其中掺杂着失败，那也是永远胜于与那些既没有享受多大快乐也没有遭受多大痛苦的平庸之辈为伍，因为他们生活在一个既享受不到胜利也遭遇不到痛苦的境地里。

For the first time ,AgBr organosol was obtained by using oleic acid to extract and modify the AgBr nanoparticles in hydrosol. And the optimum molar ratio of oleic acid to AgBr nanoparticles was found. AgBr nanoparticles, modified by oleic acid were mixed with MMA. After polymerization was carried out, the polymeric photochromic material was synthesized.

首次采用油酸萃取并包覆了水溶胶中的AgBr纳米粒子，制备了AgBr有机溶胶；并找到了萃取率最佳时的油酸与AgBr的摩尔比；再将油酸包覆的AgBr掺杂到甲基丙烯酸甲酯中，进行本体聚合，从而制备了AgBr光致变色有机玻璃。

As for CdSe quantum dots with the same size, we found that the inclusion of Mn ions in the dots will magnify their paramagnetism at low temperature, and the size effect will be quenched.

Mn的掺杂行为同时会破坏电子轨道运动贡献的顺磁矩与抗磁矩，使得磁化率在不同温度下由小磁场到大磁场的偏移变小，量子点的磁性尺寸效应将被减弱。

The former two materials are introduced in terms of band width, photoluminescence characteristic and PL mechanisms.

着重从宽带的获得、发光性能的改善和发光机理的探索3个方面介绍了稀土掺杂玻璃和薄膜材料的研究进展。

They include photosensitization of semiconductor by use of organic dyes, precious metal deposition, cation doping of TiO2 and coupling of two semiconductors with different energy levels.

详细介绍了用贵金属沉积、有机染料敏化、过渡离子掺杂、半导体耦合等方法对纳米TiO2进行修饰改性的研究现状，展望了纳米TiO2的光催化应用前景，指出了存在的问题和今后的研制方向。

While in CZ Silicon, there are many polyhedral oxygen precipitates generated, and the size of OSFs increased with the oxidation time.

这表明，高浓度的硼掺杂原子对氧沉淀的促进作用，以及RTP预处理过程中空位体浓度的增加是导致不同缺陷产生的主要原因。

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。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
