摘　　要：通过一组假体人的高温现场实验数据对多层介质中热传导规律进行了教学设计研究。在建立多层防护服的热传导定解问题模型过程中以及在引入有限差分算法对所建立模型进行求解的过程中,设计了逻辑上递进的子问题。通过这些问题的思考引导学生对实验数据进行更深入地思考,达到有效分解细化研究进程的目的。This paper has studied the teaching design of heat conduction in multilayered medium by a group of experimental data of prosthetic body in high temperature. This paper has designed sub-problems that are logically progressing, in the process of modeling the definite problem of heat conduction in multilayer protective clothing, also in the solution process of the model based on finite difference algorithm. The students are guided to explore the experimental data more deeply through pondering these problems, thereby achieving the target of decomposing and refining the research process in an effective way.
