摘要
文章从电场对点电荷的作用力出发,阐述了电场强度定义的操作条件,指出电场对点电荷作用力表达式中的场强应为点电荷放入电场后,除点电荷以外所有其它电荷在点电荷放置处所激发的场强。
The paper introduces the operation conditions for the electric field intensity, and states that the intensity in the formula about the effect force of the electric field on point charges is the one initiated by other charges except the point ones after the point charges have been put in the field.
