摘要
文章通过分析利用电势与电场强度的微分关系求均匀、非均匀带电圆环轴线上的电场强度,探讨了在已知某一轴线上电势分布情况下求轴线上电场强度的方法,得到了电场强度在轴线上的投影是电势在该轴线上的变化率的结果.
By analyzing the differential relation between the electric potential and electric field intensity,we solved the electric filed intensity on the axis line of the uniform and non uniform charged circles,and discussed the method to solve the electric filed intensity on the axis line when the electric potential distribution on the axis line was known.We obtained that the projection of electric filed on the axis line was the gradient of electric potential on that axis line.
