摘　　要：稳定传热是建筑热工学中的基本传热过程,一般通过公式计算来求解。本文利用稳定传热中热流强度q处处相等的特点引入图解法,即在以热阻-温度坐标系中,绘制贯通平壁的温度分布线,利用该线进行求解。通过实例说明图解法有理论依据,结果准确,图形直观,可行性强。The steady heat transmission is the basic form in architectural thermal engineering. It usu- ally can be worked out by calculation. This article introduces the graphic method based on the charac- teristic of equivalent heat flow intensity q. It is a line in the heat resistance - temperature cord, which can be used to solve problems. Through the examples, the graphic method has theoretical basis, a- cute result, visualized figure and strong feasibility.

关 键 词：稳定传热 热阻 热流密度 温度分布线
