摘要
运用场的叠加原理和椭圆积分的理论和方法,导出了线电荷椭圆环中心轴线场强分布的解析表达式,进行了有关的讨论,指出线电荷椭圆环中心轴线场分布具有的重要特性.
Using the superposition principle of the electric field and the methods of theory of elliptic integrals and the mathematic trick, we obtain the electric field distribution in the central axis line generated by an elliptic ring uniformly charged and we make the discussion about it. The important properties of the electric field distribution in the central axis line generated by an elliptic ring uniformly charged are shown.
