摘要
论述了电场与磁场本质上的统一性质 ,构造了三维空间中电磁场的统一场量 ,给出它的方程、场量的模方与能量和动量的关系 ,发现三维空间中的统一场量自身的标积竟然是相对论变换下的不变量 .
The unified nature of electric and magnetic fields is discussed.A unified electromagnetic field vector is formed in the 3 d space.Its equations,and the relations between square of the field vector and energy,momentum are given.It is found that the dot product of the unified field vector with itself in the 3 d space is a relativistic invariant.
