电介体

PMW-PT, PNW-PT and PMW-PNN-PT ceramics with pure perovskite structure were prepared by the Semichemical Method or the Hydrothemal-Derived Precursor Method.

采用半化学法或水热前驱体法制备了纯钙钛矿结构的PMW-PT、PNW-PT和PMW-PNN-PT基弛豫铁电陶瓷粉体，探讨了钙钛矿相陶瓷粉体的形成机理，系统研究了各种影响因素对粉体或陶瓷的相组成、显微结构和介电性能的影响。

The conventional linear theories describe the linear part of the interaction between beam and wave very well.

等离于体平衡态分布与微波场有关，并且其介电特性随电场不是线性变化，因而是一非线性的栅。

A decrease in Qef value (x = 0 ~ 0.10) with increasing x was dominated by a decrease in the degree of 1:2 order. A increase in relative dielectric constant (x = 0 ~ 0.50) and the positively change of temperature coefficient of resonance frequency (x = 0.10 ~ 0.50) with increasing x were dominated by a decrease in the proportion of [NbO6] octahedra.

扭曲的 [NbO6] 八面体之比率主导本系统之相对介电系数随著 x 的增加而升高以及 x = 0.10 ~ 0.50之共振频率温度系数随著 x 的增加而往正的方向变动的趋势。

220V or General 55kw, 50 Hz power, after the abnorma circuit produced 20 ~ 30 kV, 15 ~ 20 kV high voltage and high frequency current, applied to a pair of commonly used as a dielectric is one of the interval for the eleotrode to form the silent dispersoids violet glow discharge.

220V或380V、50Hz的常规用电，经可控硅式电路产生20～30kV、15～20kV的高压高频电流，施加在一对以介电体为间隔的电极上，形成无声弥散蓝紫色辉光的放电。

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。
