从最大功率传输定理出发，逐步推演出磁谐振耦合无线能量传输的电路工作原理和特点，得到与发表在Science 等 期刊文章中一致的结论，证明磁谐振耦合无线能量传输机理依然属于电路理论的范畴，从而也说明对一些基础课程中的重要 内容进行深度挖掘和创新运用能够起到精准认识和解释当今科学前沿所报道的一些新奇现象的作用.

Starting from the maximum power transfer theorem，we deduce gradually the circuit principle and characteristics of the magnetic resonant coupling wireless energy transmission，then the same conclusion as reported in an article published in Science is obtained. It is shown that the mechanism of the magnetic resonant coupling wireless energy transfer is still in the domain of circuit theory. It also demonstrates that digging in depth and applying creatively the important contents，appeared in basic courses，can play a role in accurately understanding and explaining the new phenomena reported in the scientific foreland.
