一对等量同号点电荷的静电场线

The lines of static electric field that point charges of the pairs same class

对现行电磁学教材中,“一对等量同号电荷的静电场线”的两种表示进行了讨论,指出其中的不妥之处,并说明了电场线表示方法的优劣。

Tow form that 'The lines of static electric field that point charges of the pairs same class' are discassed in the electromagnetics teaching material in effect. It point out they's deficiency, and the explaine the merits and demerits that lines of static electric field way.
