摘　　要：应用电磁场能量转换与守恒定律于正弦稳态线性交流网络中，得出能量守恒定律的新表示式．利用式中统一体现的电阻、电容、自感和互感４种元件能量形式的优点，以及网络现代场论关于元件复阻抗率和积分形式的复阻抗等概念，分别给出４种元件具体的积分形式复阻抗．通过复阻抗与电压、电流的关系，与电路的串并联联系起来，导出包含互感元件的４种元件串联后再串并联的复阻抗公式，并验证此公式的正确性．By applying the law of energy transformation and conservation in electromagnetism to a sinusoidal steady state linear exchange network,the aauthors obtain a new expression of the law in which the merits of such energy forms as resistance,capacitance,self induction and mutual induction of four kinds of elements are embodied.By using these merits in this new expression and such concepts of network modern field theory as rate of complex impedance of the element and complex impedance in integral form,the specific complex impedances in integral form of four kinds of elements are given respectively.By linking the relationship of complex,voltage and current with the series parallel connection of circuit,a formula of complex impedance is derived for four kinds of series and then series parallel elements.The correctness of the formula is verified.
