摘要: Presents experimental results which show that a wall in contact with dense hot metal vapour injects very-high-density current. In the same way, at root of cathode spot density is very high and calculation made enhancement electron emission due to lowering work-function caused by polarisation energy excess electrons vapour. A relation established allows be determined thus rate evaporation out any material.
