相对论时空变换下Maxwell电磁场方程的协变性

The Covariance of Maxwell Electromagnetic Field Equations in Relativistic Space-Time Transformation

在Einstein的狭义相对论中,电磁场在不同惯性系之间的变换是和Maxwell电磁场方程的协变性紧密相关的.采用矢量运算,在分析Maxwell方程具有协变性的同时,给出电磁场的基本物理量■、■、■、■的相对论变换公式.这种电磁场的相对论变换是交叉变换,体现了电场与磁场内在的统一性和不可分割性.

In Einstein＇s special theory of relativity,the transformation in different inertial frames of electromagnetic field is closely related the covariance of Maxwell equations.In this paper,the covariance of Maxwell equations was analyzed,and the relativistic transformation formulas of the basic physical quantities ■、■、■、■ were given.The relativistic transformation of the electromagnetic field is the cross-conversion,which reflects the inherent unity and indivisibility of electric and magnetic fields.
