【 摘 要 】

Electrostatic phenomenawere discovered long ago but their interpretation according to well-establishedatomic-molecular theory is still lacking. As a result, electrostatic phenomenaare often irreproducible and uncontrolled, causing serious practical problems.Highly reproducible recent experimental results on electrostatic charging fromthis and other laboratories are reviewed in this work, together with a descriptionof the relevant but not so usual Kelvin probe and Faraday cup techniques. Theseresults support a new model for electrostatic charging of dielectrics and insulatedmetals, based on the role of moist atmosphere as a charge reservoir.
