摘　　要：本文通过对落地式火炕模型已有研究内容进行分析和整理,建立了火炕内部传热的基本通用数学模型,该模型计算的结果,炕面温度非均一,更符合实际火炕特点。作者首先确定了具体的火炕的物理结构模型,之后建立了的火炕传热数学模型,并通过已有的实验数据,对模型进行了验证,证明该火炕热工性能模型的可用性。This article analyzed the existing research content of Chinese kang. The basic general mathematical model of heat transfer was established. Through the results of the model calculations, a non-uniform kang surface temperature was gotten which is more in line with the actual characteristics of the kang. At first the physical structure of the model was determined, then the basic general mathematical model was established. Through the existing experimental data, the model was verified. It proved that the mathematical model is reliable.
