摘　　要：针对非均匀介质中的电磁场,结合一阶偏微分场方程和介质的物态关系,从稳恒场到时变场,研究定解方程的建立过程,集中给出不同场合下定解问题中变系数非齐次偏微分方程的各个具体形式,为求解相应电磁场问题提供理论基础.Aiming at the electromagnetic field in inhomogeneous medium,the establishing process of definite equations is investigated,combing with the first-order partial differential field equation and state relation,from the steady field to the time-varying field,the various forms of inhomogeneous partial differential equation with variable coefficients are given conceptually,which provids a theoretical basis for solving electromagnetic field problems.
