等量异号带电板电场的讨论

ELECTRIC FIELD OF UNSYMMETRIC PLATES WITH EQUAL AND OPPOSITE CHARGES

现有的物理教材，关于等量异号带电板的电场，只讨论了带电板对称轴或对称面上某点的电场强度，而任意点的电场强度、电位，一般没作详尽的讨论，本文利用了电偶极子的电场，以及电场强度与电位梯度的关系，讨论了非对称轴或对称面上任意点的电场强度、电位。同时推导出其电力线方程和电位线方程。

In the physics textbook conventionally used,the electric field for plates with equal and opposite charges is only studied for the case with symmetric axis or symmetric surfaces.In this paper,the point strength in the case of plates without symmetric axis or non-Symmetric surfaces are studied.The force line and potential gradient equation are deduced.
