摘　　要：在电磁场与电磁波及后续微波技术的相关课程中,正弦电磁场是主要的研究对象。为了数学表达和分析的简化,场及其相关方程通常用复数形式表示。教学过程中,笔者发现关于场能量的相关物理量及方程的复数表示存在特殊性,给教和学带来困扰。针对这个问题,本文自定义了“复数化过程”这一概念,基于此概念,梳理了与场能量相关的物理量及方程的复数表示,为相关教师的教学和学生的学习提供一个有效参考。In the related courses of electromagnetic field,electromagnetic wave and subsequent microwave technology,the sinusoidal electromagnetic field is the main research object.In order to simplify the mathematical expression and analysis,the field and its related equations are usually given in complex form.In the process of teaching,it is found that the complex representation of the relevant physical quantities and equations of field energy has particularity,which brings trouble to teaching and learning.For this problem,the concept of“pluralization process”is defined in this paper.Based on this concept,this paper combs the complex representation of the physical quantities related to field energy so as to provide an effective reference for relevant teachers’teaching and students’learning.

关 键 词：正弦电磁场 复数表示 平均能量密度
