| Abstract: | The dynamic equation describing the relationship between surface charge density and voltage is established. The time constant of charge accumulation is introduced. The present theoretical analysis explains why surface charging occurs under impulse voltage, and finds out the factors that influence the process of charge accumulation. The result is supported by the measurements in some previous investigations. |
