绝缘击穿电压

The basic principles for largely aperture PEPC with thinness crystal plane have been expounded.2. It is the first times to use horniness anodize aluminum film as the isolator of plasma in P.R.China. The life-time and breakdown voltage of anodize aluminum film have been tested.

国内首次成功将硬质阳极化膜用于等离子体绝缘，实验研究了阳极化膜的寿命和击穿电压特性；将等离子体绝缘的最低阳极化膜厚优化到了60μm(美国LLNL的选择为100μm)，解决了国内工程实施的可行性问题。

In evaluating the dielectric strength of gases and gas mixtures, the com- monly used method, i.

通常采用的评定气体和混合气体耐电强度的方法，即将均匀场间隙中测得的击穿电压与参考气体相比，实际上并不能反映不同气体在工程应用中绝缘性能的优劣。

AC voltage endurance test of secondary circuit:voltage for test is 1000V,when insulation resistance of circuit is above 10M,we can use megohmmeter of 2500V for replacing,test time is 1 minute,take measures to prevent overvoltage and dielectric puncture during test.

3.10.1.3 二次回路交流耐压试验：试验电压为 1000V，当回路绝缘电阻在 10M 以上时，可用 2500V 兆欧表代替，试验时间为 1min，试验时应采取措施防止过压击穿。

Based on the discussion of some problems, it is pointed out that mountingadditional lightning arrestors on both ends of overhead lines is an effective means toprotect outlet CB of substations.

就事故分析提出了几个值得探讨的问题：事故与断口两侧有工频电源有关；雷击波的陡度值处于外绝缘大于内绝缘的区域和电压抽取装置的削波作用不显著而使灭弧室内绝缘击穿；外绝缘先击穿或内、外绝缘同时击穿；事故与雷击进线段发生绕击或反击的关系是主要的还是次要的。

The influence of oscillator plate voltage, gas pressure, extraction voltage, focusing voltage and magnetic voltage on the quality of ion beam is determined and analyzed.

发现在0.6MPa以上时，N_2和CO_2的击穿电压增加趋势逐渐变缓，而混合气体的击穿电压仍呈直线增加；加入六氟化硫可明显提高绝缘性能；湿度对击穿电压影响不大。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
