摘要
对于电磁场中的能量是否守恒,关系到信号的完整度以及与电磁的兼容性,为此研究电路中的能量守恒较为迫切。基于此背景,以电容开关电路为研究系统,坡印廷理论为基础,研究了该系统开关CK闭合前后电路中元器件电荷以及能量守恒问题,得出了电路传输时总能量守恒的结论,为电磁场能量守恒研究提供了一定的理论支撑。
Whether the energy in the electromagnetic field is conserved is related to the integrity of the signal and the compatibility with the electromagnetic. Therefore,it is urgent to study the conservation of energy in the circuit. Based on this background,the research system based on capacitive switch circuit,the Poynting theory,studied before and after the switch CK is closed and the circuit components in charge of energy conservation and the problems of the system,draws the conclusion that the conservation of total energy transmission circuit,provides a theoretical support for the study on electromagnetic energy conservation.
