摘　　要：基于傅里叶导热基本定律．采用固定热面温度、测定非稳态过程冷面温度及积分法测定传导热量的方法，建立导热系数的简单测定方法。对冷面温度和测得的导热系数进行回归分析得到0℃时的导热系数及温度系数。此方法及基于此方法研制的仪器用于导热系数测定，测定结果与资料的给定值一致。Based on Fourier＇s law of heat conduct theory, the method for determining coefficient of thermal conductivity was established by fixing the hot side temperature, determining cold side temperature and integrating the heat conducted from the hot side. The coefficient of thermal conductivity on OK and temperature coefficient of it can be deducted, and the value is coincident with the given one.
