| 摘 要： | 伟大的物理学家牛顿首先提出了力学惯性定律:"每个物体将继续保持其静止或沿一直线做匀速运动状态,除非有力加于其上迫使它改变它改变这种状态."而本文则在电磁领域提出相应的电磁惯性-每个电磁波都倾向于保持球三维或圆二维状态向外传播,除非有外加源或边界迫使它改变这种状态.文中,还把这一思想进一步扩展为电位ψ和电荷σ的静电惯性.

| Abstract: | I.Newton,a great physical scientist,first proposed the law of force inertia: a body will remain in its state of rest or of uniform motion in a straight line untile was acted upon by an external force to change the state.This paper presents the electromagnetic inertia that a electromagnetic wave will spreed with the tendency of a sphere in 3-dimensional or a circle in 2-dimensional unless external source or boundary was acted to change the state.This idea is extended to electrostatic field of electric potent... |
