摘　　要：麦克斯韦方程组的协变形式与两个相对论不变量是狭义相对论和电动力学中非常重要的内容,一般文献和教材中对于这两个问题的处理要么强调数学推导,要么注重理论解释.尝试从物理概念到数学结构的理念出发得到这两个结论.这无疑对狭义相对论的理解有一定的帮助,也是学习量子场论、粒子物理学必须具有的基本知识和推证能力.The covariant form of Maxwell＇s equations and the two relativistic invariants are important elements in special relativity and electrodynamics. These two problems are dealt with in general literature and textbooks either by emphasizing mathematical derivation, or by focusing on theoretical explanations. Two conclusions are attempted to be reached by starting from the physical concept to mathematical structure, which renders help to the understanding of special relativity, and provides the basic knowledge and reasoning ability to learning quantum field theory, particle physics.
