【摘要】 在似稳场的某些电磁过程中,磁感应强度容易引起超距作用的困惑,然而引入矢势可以解除这种困惑,说明具有不可替代的作用。量子理论中的A-B效应,不但证明了是比更基本的物理量,而且也说明了微观世界也同样不存在超距作用。更多还原

【Abstract】 In some electromagnetic processes in the quasi-stationary fields, the stre-ngth of magnetic induction is apt to cause the perplexity of the action atadistace. However we can introduce vector potential A to remove such perple-xity, which shows that A has the fuctin that B cann’t replace for. The A-B effect in quantum theory not only proves that A is a more fundamentalphysical quantity than B, but explains that there exists no quasi-stationaryaction in the microcosmic world.更多还原
