摘　　要：提出了电阻Y形网络和Δ形网络相互等效变换式的推理记忆法。具体推理步骤有量纲推理、电路结构类比推理和公平原则推理三个方面。特别在电路结构类比推理中指出电阻Y形网络和Δ形网络与简单电阻串联网络和并联网络具有对应相似性,有助于学生联想记忆。An inference memory method is proposed for the equivalent transformation formulae of resistive Y-shaped network andΔ-shaped network.The specific inference steps include dimension reasoning,circuit structure analogy reasoning and fair principle reasoning.It is pointed out,especially in the circuit structure analogy reasoning,that the resistance Y network and theΔnetwork have similarities with the simple resistance series network and the parallel network respectively,which is helpful for students’associate memory.
