| 摘 要： | 以稳恒载流圆直导线为例，根据保证稳恒电流的电荷分布特点，指出欧姆定律微分形式中的电场强度Ｅ应是总电场在电流方向的分量。同时又指出一般情况下这一分量与总电场方向偏差很小，量值基本相等。

| Abstract: | The round straight wire with steady electric current is taken as an example.According to ensure the charge distribution character of the steady electric current,it is pointed that the electric field intensity in differential form of the law of Ohm is the component of the total electric field in the direction of electric current,and the deviation between this component and total electric field is small and their quantities are nearly equal. |

| Keywords: | the total electric field the law of Ohm magnetic force |
