摘　　要：通过对2015年高考江苏物理卷第8题理论分析,证明在d点左右两侧电场线不可能是直线,并通过数值模拟和仿真得到了3个点电荷周围电场线的分布图,与理论分析结果一致.Through the theoretical analysis of the 2015 gaokao jiangsu physics paper question 8,it is proved that the electric field lines at the left and right sides of the point d cannot be straight lines,and the distribution maps of the electric field lines around the three point charges are obtained through numerical simulation and simulation,which are consistent with the results of the theoretical analysis.

关 键 词：点电荷 电场强度 电场线
