摘　　要：先依电象法,推导均匀带电圆环在金属导体球壳内的"象电荷";再在球坐标系下,根据电场强度的计算公式与Tay-lor展开式,计算出均匀带电细圆环在全空间的电场分布的级数形式解;进而结合唯一性定理和电场的叠加原理,获得带电细圆环与导体球壳系统的空间场分布.According to the method of images, the ＂image charges＂ of a uniformly charged ring in a conducting sphere are studied. In spherical coordinate system, based on the electric formula and Taylor series expansion, the electric field distribution of the ring is obtained in a series form, then combined the uniqueness theorem and the superposition principle, the electric field distribution of this system are derived.
