摘　　要：对封闭导体壳内外电场的分布特点进行了研究,得出导体壳接地与不接地时空间各处电场的分布:不接地的导体壳,壳内的带电体对壳外的电场有影响,但壳外的电场对壳内无影响;接地的导体壳,内、外电场均无影响.并由此分布规律出发对2种典型的封闭导体球壳内外电场的分布情况进行到了详尽的分析.Electric field distribution inside and outside the closed conductor global shell is studied in the paper. The conclusion is that for the ungrounded conductor shell and electric appliance in the shell have influence on the external electric field,but the electric field outside the shell has no effect on the shell;for the grounded conductor shell,the electric appliance in the shell and the electric field outside the shell have no effect on each other. And the electric field distribution inside and outside two typical closed conducting global shell is analyzed.
