摘　　要：在线性导热系统动态特性的理论研究中引入传递函数概念 ,提出了长圆筒壁热学传递函数的理论计算方法 .用热学传递函数分析了长圆筒壁的导热动态特性 .发现长圆筒壁热学传递函数可以全面描述圆筒壁的动态导热特性 ,为对传热问题的分析提供了方便 .The concept of the transfer function is introduced into the theoretical research on the dynamic performance of the linear heat conduction system, and the theoretical method of calculation for the thermal transfer function of long cylinder is presented. Also, the dynamical property on the heat conduction of long cylinder is analyzed through the thermal transfer function. It is found that the thermal transfer function of long cylinder can describe the dynamic performance of the heat conduction, and this can provide more convenience in analyzing the heat conduction problem.
