库仑定理导出的2维空间电荷限制流一级近似公式
Deducing two-dimensional space-charge-limited flow first-level approximating formula from Coulomb's law
摘要
Abstract
Based on the Coulomb's law and the current continuity equation, this paper solutes the electric field of the charged particles group at a certain point in space, and considers a series of reasonable approximation.The two-dimensional spacecharge-limited flow first-level approximating formula in the axial symmetry column conductor is obtained.The result reveals that for a limited plane the computed charge-limited flow by the two-dimensional is bigger than that by the classical one dimension formula.关键词
