摘　　要：放电装置的设计取决于导体表面从有棱角到光滑过程中表面电荷分布规律的研究。运用COMSOL Multiphysics多物理场仿真软件构建静电场模型,定量计算平面导体从正方形演变到圆形,柱状导体侧面由有棱角演变到光滑过程中,导体线、面电荷的电荷密度,进而分析圆角化过程中导体线、面电荷的分布特征。研究结论对静电场中产品的设计以及放电装置的安置具有指导意义。Design of discharge is depended on charge distribution in the process of changing conductor suface from an- gular to smooth.Using COMSOL Multiphysics simulation software builds electrostatic field model.Linear density and areal density are quantitative calculated during the flat conductor transforms from square to round and a side of cylindrical con- ductor transforms from angular into smooth,It is analyzed that characteristic of charge distribution in the process of rounded.
