摘　　要：电力线表面电荷在周围产生强的电场,可以将电力线近似成无线长导线。文中通过镜像法推导了线电荷对于周围金属圆盘的二维解析解,建立了无限长导线薄金属圆盘的电荷分布模型,揭示了其表面电荷分布特性,为进一步揭示电力线空间电荷分布提供了理论依据。The surface charge of the power line generates a strong electric field around it,and the power line can be approximated as a long wire.In this paper,the two-dimensional analytical solution of the linear charge to the surrounding metal disk is derived by using the mirror method,and the charge distribution model of thin metal disk with infinite length is established.The characteristics of surface charge distribution are revealed,which provides a theoretical basis for further revealing the space charge distribution of power lines.
