摘要
场强积分是计算带电体场强分布的基本方法,通用教材上介绍了简单形状带电体(如均匀带电直线、圆环及圆面)场强的计算.但对于一般对称性的带电体情形并未提及.本文拟给出正多边形框及正多边形面轴线上的场强分布,并讨论了若干极限情形,取得了预期的结果.
Integral on electric-field intensity is a fundamental method to compute the electric field intensity distribution. The calculations of electric field intensity of charged objects with simple geometry,such as charged straight line, charged ring and charged circular surface, are introduced in general textbooks, while the charged general symmetrical objects are not mentioned. In this paper, the electric field intensity distributions on the axes of charged regular polygon frame and surface are introduced, and the results in critical conditions are discussed.
