摘要
矢势在量子物理中具有磁场B所不能替代的重要作用,然而在经典物理的电磁理论中矢势却只是磁场B的辅助矢量,且无直接观测的物理意义。从经典物理与量子物理的不同视角全面认识矢势具有的作用,对于正确理解矢势的意义、更好地掌握电磁场理论以及对于分析和解决实际的电磁场问题都具有重要的指导意义。
Vector Potential A has an important action in quantum physics which can not be substituted by Magnetic Field B. However, in the theory of electromagnetic field of classical physics, Vector Potential A is only the auxiliary vector of Magnetic Field B？ without any physical meaning of direct observation. A comprehensive understanding of the impact of Vector Potential A from different perspectives of the classical physics and quantum physics is of vital necessity both to an understanding of the significance of Vector Potential A and to a better grasp of electromagnetic, field theory, and is also of important guidance to analysis and solution of the practical problems in the electromagnetic field.
