From the fact that Cd-Ni storage batteries are widely used as DC power sources at small substations, the reverse polarity and activation of Cd-Ni storage batteries are discussed in detail. 针对小型变电所普遍使用镉镍蓄电池作为直流电源的现实,分析了镉镍电池的反极现象和进行活性化处理的方法。
This report describes the structure and the main behavior of a surfacing torch with reverse polarity soft plasma arc and uses alloy powder. 本文介绍了反极性(RP)弱等离子弧粉末堆焊枪的结构及其主要特征。
In this paper, the moving characteristics of cathode spots in reverse polarity soft plasma arc, the-distribution of cathode spots, current distribution and voltage distribution, the influence of energy produced cathode spots on distribution of arc energy are studied. 本文探讨了反极性(RP)弱等离子弧阴极斑点游动特性。对阴极斑点、电弧电流与电弧电压三者分布之间关系,阴极斑点能量对电弧能量分布的影响进行了研究。
American SEG defines seismic record polarity as SEG normal polarity and SEG reverse polarity. 美国SEG协会把地震剖面的极性规定为SEG正常极性和SEG反正常极性。
The high current, low voltage, reverse polarity, oxidative shielding gas, thick wire are the essential conditions of formation of the buried are, the high current being the most important factor. 大电流、低电压、粗焊丝、反极性(RP)和氧化性气氛是形成潜弧过程的必要条件,其中电流是最重要的条件。
