After ball milling, it can see the better dispensability and lower turn-on field. 经球磨后,可大略看出分散较佳之浆料,起始场发射电场有往低的趋势。
It was concluded that charge injection and recombination would restrict the field electron emission, and increase the threshold voltage of flashover and decrease its scattering. 发生在绝缘体表层的电荷注入和复合过程能够在一定程度上抑制场致电子发射,从而提高沿面闪络电压,并降低闪络电压值的分散性。
