摘要
围绕电动力学相关内容,针对介质中电磁动量及应力张量问题,依据麦克斯韦方程组、洛仑兹力及动量守恒定律等,并着力结合近年的理论研究进展,比较与分析介质中电磁动量、应力张量不同形式的区别与联系,探究其物理内涵与作用,力图为相关的教学与研究工作提供参考.
Aiming at the problems of the electromagnetic momentum and stress tensor in medium, and committed to the combination with the theoretical research progress in recent years, the distinction and relation for the different forms of the electromagnetic momentum and the stress tensor in medium are compared and analyzed. Their physical meaning and functions are explored according to the Maxwell equations, Lorentz force and the momentum conservation law. We try to provide the references for the related teaching and research work.
