摘　　要：通过求带电球壳内电场强度在内外半径趋于相同时的极限,计算了均匀带电球面上的电场强度,与利用叠加原理或虚功原理计算的结果完全相同.并对均匀带电球面上的电场强度的不连续性进行了探讨,发现这种不连续来源于将带电球壳理想化为无限薄球面的过程.By calculating the extremity when the electric field intensity in the inner and outer radius of charged spherical shell tends to be same, this paper calculated by using the superposition principle and the principle of virtual work. The uniformly charged spherical surface electric field intensity discontinuities were discussed, and it found that the discontinuous from the charged spherical shell is idealized as an infinitely thin spherical.
