摘　　要：针对目前《传热学》热电比拟实验教学中存在的实验对象单一,缺乏学生自主设计环节以及实验中变换导热研究对象或边界条件带来的实验工作量及实验成本等问题,通过Tina-II电路仿真软件模拟两种边界条件下二维墙角问题,将模拟结果与应用数值法求解获得的计算结果、热电比拟实验结果进行了对比分析。结果表明,误差在极小范围内,一致性较好。在此研究的基础上,构建了基于电路仿真软件的传热学热电比拟实验"三层阶梯式"教学模式,以期通过多环节的实验教学流程及内容设计,改进现有传热学热电比拟实验教学模式。In terms of the uniqueness of experiment and electric consumables of circuit boards in thermo-electronic analogy experiment,software Tina-II was applied to simulate heat conduction problems with isothermal and convection boundary.In comparison with the results of numerical method and thermoelectrical analogy method,this simulation’s error was shown very small and also with a relatively high accuracy.On this foundation,a three stage-separated ladder-type experimental teaching model is proposed,to echelon teaching on the basis of the circuit simulation software is proposed.It is devoted to promote the traditional general thermoelectrical analogy experiment teaching mode.
