本文首先类比全息原理引入了全息性的概念，然后从矢量场论中的斯托克斯定理和高斯定理出发对电磁学规律的全息性进行了讨论，最后结合电磁学规律的全息性对静电场、静磁场边值问题的唯一性定理以及电磁波场的边值定解问题的物理本质进行了分析.结果表明静电场和静磁场边值问题的唯一性定理以及电磁波场边值定解问题都可以认为是电磁学规律的全息性在实际问题中的具体体现，从而可以帮助学生更好地理解这些定理以及惠更斯-菲涅尔原理的物理本质.

This paper first introduces the concept of holographic property by analogy with the holographic principle. Then, starting from Stokes’ theorem and Gauss’ theorem in vector field theory, the holographic characteristics of electromagnetic laws is discussed. Finally, combined with the holographic property of electromagnetic laws, the physical essence of the uniqueness theorem of the boundary value problems of electrostatic fields and magnetostatic fields, as well as the boundary value definite solution problem electromagnetic wave fields, is analyzed. The results demonstrate that the uniqueness theorems of the electrostatic fields and magnetostatic fields, along with the boundary value definite solution problem electromagnetic wave fields, can all be regarded as concrete manifestations of the holographic property of electromagnetic laws in practical applications. This approach thereby helps students better understand the physical essence of these theorems and the HuygensFresnel principle.
