浅析电磁场的“势”

Analyses of the Electromagnetic Potentials

讨论了电磁场的各种“势”,分析了电势、磁标势、矢势、标势、推迟势、库仑势、电磁势…的适用范围,相互之间的区别和联系.指出了“运动电荷的推迟势”的说法不一定成立,阐明了量子力学要用到电磁势;在量子理论中,将电磁势看成一种数学工具而非物理现实是不对的,电磁势的物理效应是可观测的.

All sorts of elecrtomagnetic Potential are discussed. The range of applications of electric potenlial, magnetic scalar potential, vector potentiol, scalar potential, retarded potential, coulombic potential, electromagnetic potential are analysed, and point out their differences and relations. It is emphasized that ＂retarded potential of kinetic charges＂ is not quited right. The vector potential A is a kind of physics reality, not only a mathematical method in quantum mechanics. The physics effect of A-AB effect can be obserred and measured.
