静电场中，电场线为平行直线的区域内（）

A.利用高斯定理可以证明同一电场线各点的电场强度相等；利用静电场环路定理可以证明不同电场线上的场 强相等，故电场线处处平行的区域一定是匀强电场； It can be proved that the Electric Field Intensity of each point of the same Electric Field Line is equal by using Gauss Theorem, and the Electric Field Intensity of different Electric Field Lines is equal by using Electrostatic Field Loop Theorem, so the area where the Electric Field Lines are parallel everywhere must be Uniform Electric Field;###SXB###B.利用高斯定理可以证明同一电场线各点的电
