| 摘 要： | 对运动电磁场的电场强度变量和磁感应强度变量做旋度及散度运算分析，表明除电位移变量项与经典Mexwell方程组的正负号不同外，大多数时变电磁场理论下的Maxwell方程都可以在一定条件下从运动电磁场的Maxweel方程组中导出。但在有些条件下运动电磁场的Maxwell创方程组仍然可以应用，并能得到正确的结果，而经典Maxwell方程组无法应用。这说明用“运动电场具有磁场特性；运动磁场具有电场特性”来描述电场与磁场之间的关系要比时变电磁场理论更符合自然规律。时变电磁场理论的Maxwell方程组是运动电磁场在特殊条件下的特殊形式。所谓时变电磁场可能是运动电磁场在特殊条件下的特殊表现，时变电场与时变磁场之间的相互转化可能是运动电磁场在特殊条件下所表现出的假象，并非电磁场的真正规律。时变电磁场理论的Maxwell方程组作为数学工具在一些领域中可以应用，但作为原理表达式，它们不是每个都正确的，也不是总对的。

| Abstract: | The results of divergence and curl calculation on the electric field intensity variable and magnetic induction variable of the motional electromagnetic field have shown that almost all the classical Maxwell's equations of time-varying electromagnetics theory can be deduced from the Maxwell's equations of moving electromagnetic field in some special conditions.This suggests that the classical Maxwell's equations, which have been believed to be the general and fundamental law by classical electromagnetics, is only a special results of calculus of motional electromagnetic field at special condition. And the following formula is a more general relationship between electric field and magnetic field than the classical Maxwell's equations.E=B×VBB=(1)/(c2)(VE×E)The classical Maxwell's equations of time-varying theory still can be used as mathematics tools in some area, but they are not every one is right in principle, and they are not always right. The so-called time-varying electromagnetic field is only a special case of moving electromagnetic field. And the transformation between electric field and magnetic field at time-varying condition may be a special phenomenon. |
