提出了二次发射多孔电介质中场增强自持电子发射的模型。结果表明，金属-多孔介质界面上形成一次电子的机制是金属的场发射，二次电子的雪崩形成导致层内场的重新分布，从而形成场发射所需强度的电场。
A model is proposed for field-enhanced self-sustaining electron emission in secondary-emission porous dielectrics. It is shown that the mechanism for the formation of primary electrons at the metal-porous dielectric interface is field emission from the metal, and the electric field of the required intensity for field emission is formed by redistribution of the field in the layer as a result of the avalanche formation of secondary electrons.
