The solvents commonly used in the solvothermal synthesis include alcohols (such as methanol, ethanol, isopropanol, alcohol, ethylene glycol, glycerine, etc.), amines (such as hexamethylenediamine, dimethylformamide, triethanolamine), Acetonitrile and Propionitrile, the differences of functional groups, varieties of kinds together with a wide differences of polarity, dielectric constant and boiling point of organic solvents greatly increase the diversities of the product.

溶剂热合成常用的溶剂有醇类(如甲醇、乙醇、异丙醇、正丁醇、乙二醇、甘油等)，胺类(如己二胺、二甲基甲酰胺、乙醇胺)，乙腈和丙腈等，有机溶剂由于带有不同的官能团，种类繁多，具有不同的极性、介电常数、沸点等，大大增加了合成产物的多样性。

The above pyrochlore concentration is acceptable for dielectric applications and is unlikely to result in an obvious harmful effect.

实际上，过分追求钙钛矿相的纯度往往会以牺牲其它性能为代价，包括使工艺流程复杂化、成本上升等，甚至对介电性能本身的改善也并非有很可观的效果，因此是得不偿失的。

Effect of CuO addition on structure and dielectric properties of monoclinic pyrochlore phase ceramics was investigated.

在三元系单斜焦绿石相微波介质陶瓷Bi2(Zn1/3Ta2/3)2O7中添加不同量的CuO，研究其对材料的结构和介电性能的影响。

According to the preview study, the low dielectric constant will reduce the self-oxidation of the pyrogallic, which lead to the result of the lower self-oxidation rate in vesicles than that in solutions.

根据前面的研究结果，低的介电常数会抑制其自氧化，因此就出现了在囊泡中自氧化速率低于在水溶液中的现象。

The activty of SOD in vesicle solution is then determined. But still no apparent superactivty is found due to the following reasons: 1. The lowered dielectric constant reduces not only the self-oxidation rate of pyrogallic, but also the activity of SOD; 2. There are no efficient enough interaction between vesicles and SOD.

在上述体系中进行的SOD的活性研究中，没有发现表观超活性，估计是两方面的原因：一是囊泡周围低的介电常数同样也降低了SOD酶的活性，二是由于表面活性剂浓度较小，仅为0.5％左右，使得囊泡体积分数较小，不能与SOD酶发生充分有效的结合。

The previous research mainly depends on the arc voltage to estimate the arc position, and testing the dielectric recovery strength, and reignition process to judge the ability of arc extinguishment.

以往的研究工作主要根据电弧电压波形来判断电弧大概的位置，利用介质恢复强度测试和大量的重燃试验来判断低压电器的熄弧性能。

Finally, the MLCC (Multi-Layer Ceramic Capacitor) chips after different duration of reoxidation process were utilized to analyze dielectric performance and oxidation of Ni inner electrodes. The results showed that the formation of NiO would result in the discontinuity of Ni electrode and further degrade the capacitance and IR of the chips.

最后，本研究将制作完成的多层电容元件，经过不同补氧时程的处理，结果显示镍电极的氧化，会造成电极的不连续情况，以及降低电容和绝缘电阻值。

光滑喷口壁面吹弧气体的流动表现为层流；凸凹不平的喷口壁面吹弧气体的流动表现为湍流；对存在有湍流的不同喷口，湍流发展得越充分，越有利于控制超音速流的发展，从而有利于提高介质强度恢复速度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
