摘要:
超光速研究是物理学中的一个前沿。本文研究了与纵向电场相关的超光速问题, 讨论了直流电路中金属导线内的纵向电场以及电能的传输过程。在导线内,静电场的电势差驱动了电子,形成了电流,电子的势能转化为电子的动能,消耗了电功率。同时,电池的化学能产生了电动势,补充了电能,完成了能量的转化和守恒。在直流电路的情况,坡印廷矢量仅仅是一个数学定义,没有形成真实的能流。直流电能完全是在金属导线内传输的。从理论上讲,纵向电场是非局域的,也就是说,纵向电场的速度可以无限大。这篇论文给出了测量纵向电场瞬态速度的初步实验结果。

Abstract: Research on superluminal phenomenon is a frontier of physics. The problem of superluminal as-sociated with the longitudinal electric field is studied in this paper. It discusses the longitudinal electric field inside the metal wires and electrical energy transmission in DC circuits. In the metal wire, the difference of electrical potential drives the electrons and then forms a current. The po-tential energy of electrons is converted into kinetic energy. This process completes the cycle of energy conservation. In the case of the DC circuit, Poynting vector is just a mathematical definition, and there is no real energy flow. DC power is transmitted entirely in the metal wire. Theoretically, the longitudinal electric field is non-local, that is, the speed of the longitudinal electric field can be infinite. It gives the preliminary results of an experiment to measure the transient speed of longi-tudinal electric field in this paper.
