摘要: 在稳定热源流过多层介质材料的传热过程中，温度会随时间和位置发生变化。本文分析了稳定热源通过多层介质传热的温度分布，运用热传导方程导出了热稳定后的温度分布以及最内层材料温度随时间的变化关系。本文的方法适用于多种隔热材料的复合问题，可求出多层介质各层温度随时间的变化规律。

Abstract: The temperature changes with time and location for heat transfer with steady heat source flowing through a multi-layered dielectric material. In this paper, the temperature distribution of steady heat source flowing through a multi-layered medium is studied. By using heat conduction equation, we derive the heat-stable temperature distribution and the temperature regularity of the innermost material changes as time. Our method is applicable to the composite problem of various thermal insulation materials, and can be used to determine the temperature distribution of the multi-layered medium material.
