| 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 and straight wire with steady electric current is taken as an example. According to the charge distribution character ensuring the steady electirc current, it is pointed that the electric field intensity E in differential form of the Ohm's law is the component of the total electric field in the direction of electric current, and the deviation between the component and total electric field direction is quite small and their quantities are nearly equal. |

| Keywords: | total electric field Ohm's law magnetic force |
