稳恒电流的导体中能量传输问题

The Problem of Energy Transfer in the Conductor with constant currene

本文首先定性地分析了稳恒电流通过导体时产生的电场和磁场,以图形方式展示了电路中能量传输的图景.第二部分又定量的分析了稳恒电磁场在真空中的能量分布和传播问题.由此懂得了不是电源直接作用于用电设备为人类服务,而是通过电磁场的能量传输才起作用的.

In this paper,we qualitatively analyzed the electric and magnetic fields generated when there was constant current in the conductor,displayed the energy transmission prospect in graphics mode in the first part.In the second part,we quantitalively analyzed the energy distribution and spread of steady electromagnetic field in a vacuum.It is not the power having the effect on the electrical equipment,but the electromagnetic field by energy transmission hauing the effect on the electrical equrpment.
