摘要: 考虑一类多参数的2×n Fan电路网络模型,该网络水平轴线的下边界为一条导线,其余水平与竖直轴线上的电阻为3种独立的元件,这是一个之前没有研究过的新问题.本文采用基于节点电压为参数的递推-变换方法(RT-V)开展研究,通过严格的理论计算推导出了水平轴线上任意节点的等效电阻解析式.文章进一步讨论了特殊情形下的结论,验证了理论结果的正确性.本文的研究结论可以为相关的应用研究及其它跨学科的仿真研究提供新的理论依据,其研究工作对培养大学生的创新实践活动具有积极意义.

Abstract: A class of multi-parameter 2×n Fan circuit network models is considered, the lower boundary of the horizontal axis of the network is a single wire, and the resistors on the remaining horizontal and vertical axes are three independent components. This is a new question that has not been studied before. In this paper, the Recursion-Transform method (RT-V) based on node voltage as the parameter is adopted for the research. Through strict theoretica calculation, the analytical formula of the equivalent resistance of any node on the horizontal axis is derived. The article further discusses the conclusions under special circumstances and verifies the correctness of the theoretical results. The research conclusion of this paper can provide new theoretical basis for related applied research and its interdisciplinary simulation research. The research work also has positive significance for cultivating college students' innovative practical activities.
