结果表明，随着电压的升高，六硼化镧放电管的放电机理由辉光放电转变为弧光放电，放电电流突然迅速升高，管压降大幅下降。

The results show that as the voltage rises , the tubes ' discharge mechanism changes from glow discharge to arc discharge , the current rises suddenly and the voltage drops a lot .

在同样的氧化条件下，六硼化铈在空气中比六硼化镧容易氧化。

It seems that cerium hexaboride is more easily oxidized than lanthanum hexaboride under the same oxidation conditions .
