电荷间力和偶极辐射的时空变换性质:相对论电动力学经典场概念的崩溃
Space-time transformation properties of inter-charge forces and dipole radiation: Breakdown of the classical field concept in relativistic electrodynamics
摘要:
详细研究了经典电动力学和最近发展起来的相对论经典电动力学理论中电荷间相互作用力及其电场和磁力场的时空变换性质。重要的差异被发现和严重的错误被发现在传统的处理特殊的相对论效应在经典电磁学。与辐射过程相关的领域也被认为是经典和量子力学的预测进行了比较。一个重要的,虽然微不足道的,数学错误的推导延迟Liénard-Wiechert延迟潜力指出。它还表明,为什么移动源电荷或电流分布所产生的电场和磁场不是“经典场”,而且它们一般不构成反对称的二阶张量,因为通常假设。
英文摘要:
A detailed study is made of the space-time transformation properties of intercharge forces and the associated electric and magnetic force fields, both in classical electrodynamics and in a recently developed relativistic classical electrodynamical theory. Important differences are found and serious errors are found in the traditional treatment of special-relativistic effects in classical electromagnetism. Fields associated with radiation processes are also considered and classical and quantum mechanical predictions are compared. An important, though trivial, mathematical error in the derivation of the retarded Liénard-Wiechert retarded potentials is pointed out. It is also shown why electric and magnetic fields produced by moving source charges or current distributions are not `classical fields', and that they do not, in general, constitute an antisymmetic second-rank tensor, as is usually assumed.
