晶体

The third chapter contains my research work, which mainly focuses on Planar Photonic Bandgap. The idea of how to miniaturize Planar Photonic Bandgap by using spiral structures is proposed. Finally, by using ununiform method, the bandwidth, which is decreased due to miniaturization, are enlarged obviously.

首先介绍了平面光子晶体在微带线结构中的几种应用；然后阐述了我们在平面光子晶体小型化设计中所做的一些工作，包括仿真方案的选择，设计方案的制定与比较，以及与传统结构的比较；最后介绍了采用渐变周期结构对小型化所带来的带宽减少问题所做的改善工作。

Based on the theoretical analyses of the magneto-optical properties of a Bi4Ge3O12 crystal, the Verdet constants of a BGO crystal at different wavelengths are measured employing the double frequency method. And the experimental results agree with the theoretical value.

在理论分析Bi4Ge3O12晶体磁光特性的基础上，利用倍频法测量了不同工作波长下BGO晶体的费尔德常量，获得了与理论相符的实验结果。

Combine the measured absorption coefficients with the relations between the Verdet constant and the light wavelengths, the magneto-optical figure of merit of the BGO crystal is presented.

同时根据BGO晶体费尔德常量随波长的变化关系曲线，通过对该晶体吸收系数的测量，得出了其磁光优值曲线。

The captain and his colleagues float close to the crystalloid carefully. The webby trails from their spacesuit are around the crystalloid in a mass.

上校和同事们谨慎地向晶体靠近，他们太空服上推进器的尾迹像条条蛛丝把晶体缠在正中。

See Plate 4 in Weste and Eshraghian for another example of legged transistors (the transistors connectedto the pad are legged by a factor of four; a note to this effect appears at the bottom of the plate).

课本彩色图四也是分叉电晶体的另一个例子(连到接脚的电晶体被分叉成四个，这个效应的注解写在图页的下方)。

He wants to make it crystal clear that he doesn't agree with us.

他想清楚地表明他不同意我们的意见。3。晶体的，用晶体的

The different photonic crystal structures with different chirped coefficients, and with different apodized functions are compared.

分别对不同啁啾系数的光子晶体结构和不同变迹形式的光子晶体结构进行了比较分析。

Ostwald ripening is a key mechanism in the destabilization of emulsions (for example, by creaming and sedimentation).

同时最近几年，Banfiled又提出了一种新的晶体生长机制也能形成单晶结构，oriented attachment，多个取向不一致的单晶纳米颗，通过粒子的旋转，使得晶格取向一致，向后通过定向附着生长使这些小单晶生长成为一个大单晶，当然定向附着的过程出难免会出现一些位错和缺陷，这种生长机理形成的单晶的特点同Ostwald ripening不同，OR形成的单晶大多是规则的，给材料本身晶体结构相关，而OA形成的单晶结构在形貌上则没有限制，任何形状和结构的单晶材料都能通过此机理形成。

The results show, Sodium hexametaphosphate is the best disperse, purified and decolored reagent, which can disperse attapulgite into nano-class crystal by absorption, electrochemistry and chemical treatment, separate other mineral impurity effectively, react with main colored ion into phosphate deposition achieving decolor aim.

研究结果表明，六偏磷酸钠是凹土矿良好的分散提纯和脱色剂，它通过吸附、电化学作用和化学反应使凹土晶体充分分散为纳米级晶体颗粒，使包裹其中的其他矿物杂质有效分离，并与凹土中的主要带色离子生成磷酸盐沉淀使凹土色泽变白。
