【摘要】 本文从库仑定律和比沙定律出发,直接用del算符对场量进行运算得出场方程的微分形式,以此表示场的基本方程是从实验规律出发对场的本质更为普遍化的概括,并指出在两种不同媒质的交界面处场方程的微分形式不再适用。更多还原

【Abstract】 In this paper, starting from the Coulomb’s law and the Biot-Savart law and calculating field quantity with del operator directly,the differential presentation of field equations is obtained. It is invalid at a surface of discontinuity.更多还原
