摘要
本文以电力线方程和静电场方程为基础,研究了电场强度为零处的电力线行为,对正确运用电力线描绘静电场进行了深入探讨。
Basing on the equation of electric force line and the equation of electrostaticfield,this paper studies the behaviour of the lines of electric force of the fieldat the point of ē=0,and discusses in detail how to depict electrostatic fieldsproperly with force lines.
