| 1. | Test method for breakdown strength of organic film for use in capacitors 电容器用有机薄膜击穿强度试验方法 |
| 2. | Ac breakdown strength 破?强度 |
| 3. | Rubber , vulcanized - determination of electrical breakdown strength and voltage resistant at commercial power frequency 硫化橡胶工频击穿电压强度利耐电压的测定方法 |
| 4. | When the voltage exceeds the breakdown strength for a given insulation system , undesirable conduction paths will be created and the system will be either temporarily or permanently disabled 当电压超过确定绝缘系统的击穿值时,将出现预料之外的电流路径而且这个绝缘系统将暂时或永久地停止作用了。 |
| 5. | Having reacted with copper , paa becomes complex . the complex decomposes after heat treating and cause the increase in dielectric constant and reduction in dielectric breakdown strength . otherwise cu2o and cuo emerge from the complex , too N与cu反应后,形成络合物,热处理时自身降解,击穿强度降低,介电常数提高; cz在热处理后从络合物离解出来形成cllo和cuzo 。 |
| 6. | On the basis of relative literatures published in recent years , the effects of nano - fillers on the corona - resistance , breakdown strength , volume resistivity and dielectric properties of polymer nanocomposites are reviewed , the future research direction is also pointed out 在综合国内外近年来公开发表的相关文献基础上,对无机纳米粒子的填充对聚合物材料在击穿强度、体积电阻率、介电性能以及耐电晕等方面的研究进展进行了评述,并指出今后研究的方向。 |
