本文报道了真空中氧化亚铜涂层对高密度氧化铝沿面闪络影响的实验研究。结果表明，这种涂层提高了系统的脉冲强度，并消除了在直流和60 Hz电压下未涂覆的试样的情况下观察到的调节效果。所观察到的行为的解释给出的表面充电模型。据推测，在绝缘涂层的改善是由于二次电子发射产额的减少。
An experimental investigation of the effect of a cuprous oxide coating upon the surface flashover of high-density alumina in vacuum is reported. It is shown that such coatings improve the impulse strength of the system and eliminate the conditioning effect observed in the case of uncoated specimens at dc and 60-Hz voltages. An explanation of the observed behavior is given in terms of a surface charging model. It is postulated that the improvement in the insulation by the coatings is due to a reduction in the secondary electron emission yield.
