均匀带电细圆环的电场的一般分布

Space distribution of electrical field generated by a uniformly charged ring

直接由电场强度的计算公式计算均匀带电细圆环在全空间的电场分布,绘制出电场量值的空间分布图,进而讨论均匀带电圆环平面内、中心轴线上和远区的电场.

The general expression of the distribution of electrical field generated by a uniformly charged ring are obtained. The spatial distribution diagram for field magnitude is plotted. The field at the central axis, in the distant area and on the plane of the ring are discussed, too.
