| 摘 要： | 电磁场的相对论变换式是相对论电磁理论中的重要公式。本文从四维空时坐标微分算子以及电磁场矢势和标势的相对论变换式出发,根据E=-▽φ-βA/βt和B=▽×A的相对论协变性要求,给出了一种导出电磁场相对论变换式的新方法。该方法物理图像清晰,数学证明简单。

| Abstract: | The relativistic transformation formulas of electromagnetic field are important formulas in relativistic transformation theory.By the relativistic transformation formulas of 4D-space-time coordinate differential operators and vector potential and scalar potential of electromagnetic field,from the relativistic covariance of equations E=-▽φ-βA/βt and B=▽×A,a new method of deriving the relativistic transformation of electromagnetic field is given in this paper.The method＇s physical picture is clear and the mathematic tool to be used is simple. |
