摘要
本文根据我国建筑结构的特点，从传热的角度考虑，将墙体结构按重量分成重、中、轻三类，用墙体非稳态传热理论和计算机模拟计算，对方程Ｂ（ｓ）＝０的根 对反应系数的影响以及反应系数项数对传热计算的影响进行了分析，提出了在不同墙型条件下，传热反应系数项数的确定值。进一步完善了传热反应系数法。
According to the characteristics of heat transfer, the wall body strucute in Chinacan be divided into three types: heavys medium and light. Using the theory on unsteadyheat transfer, a computer simulation is performed. The effect of the roots al of equationB(s) = 0 on the reaction coefficients and the effect of the number of terms in the reactioncoefficient expression on the heat transer calculation are analyzed. The number of the termsin the reaction coefficients for different wall types are determined, that is, n=96 for heavewall, n =72 for medium wall and n=48 for light wall. Therefore, the method of heattransfer reaction coefficient is improved.
