%X Deep dielectric charging is one of the important factors that induce malfunctions and failures on geosyncronous satellites. In this paper, we present the physical mechanism for charging is introduced, the preliminary physical model and computer simulation method. The results by the model agree well with those of DICTAT, a deep dielectric charging analysis software developed by European Space Agency. The maximum electric field induced by deep dielectric charging always appears on the grounding side of the dielectric, where it's most likely for discharge to take place accordingly. For the typical high energy electron spectrum in outer radiation belt, the charging time for dielectrics is of the order of an hour.
