摘　　要：从实际工程应用角度出发,我们构建了非匀速运动介质(物体)系统中的动生麦克斯韦方程组(Maxwell’s equations for a mechano-driven media system),拟解决在非惯性系中低速变速运动介质以及介质形状和边界随时间/空间变化时电磁场的动力学演化规律.本文概括总结了动生麦克斯韦方程组理论的核心内容,包括方程组的构建背景、物理图像、基本特点、与经典方程组之间的区别和联系、求解方法、潜在应用范围等.深入探讨了动生麦克斯韦方程组和经典麦克斯韦方程组之间的四个主要区别,并提出近场电动力学与远场电动力学的基本概念.最后,对动生麦克斯韦方程组在科学和技术方面的潜在影响进行分析和展望.Starting from the practical engineering applications,we derived Maxwell's equations for a mechano-driven,media system(MEs-f-MDMS)based on Galilean space and time.This expanded Maxwell's equations should reveal the dynamics of an electromagnetic field for a general case,in which the medium has a time and or space-dependent volume,shape,and boundary and may move in an arbitrary,slow-moving velocity field v(r,t).This paper systematically reviews the studies and theories of the MEs-f-MDMS,which includes the basic construction background,physical picture,the essential differences and relations of the classical Maxwell's equations,solving process of the nonlinear equations,and all kinds of potential applications.Most importantly,in comparison to the existing classical electrodynamics,the newly developed MEs-f-MDMS marks four unique advances,which have been summarized and the near field electrodynamics vs.the far field electrodynamics are proposed.Finally,in this work,it also takes analysis and forecast toward this newly built MEs-f-MDMS in science and technology for the future.
