Abstract
The rate of metal evaporation under vacuum is systematically analyzed based on description of concepts about vacuum. The rate of metal evaporation increases with increase of temperature under vacuum. Three kinds of evaporation occur as vacuum changes, they are normal boiling and molecular evaporation. The rate of metal evaporation does not vary as vacuum while vacuum is high enough, that is the highest rate of evaporation, and has positive correlativity with the temperature.
