摘要
文中推导了无内热源，初始温度为常数的平壁导热传递函数．讨论了传递函数的奇点；给出了几种常用情况下的特征方程及脉冲响应函数，频率响应函数．本文的意义在于通过对平壁导热传递函数的求取及讨论，全面了解平壁的导热特性．平壁导热传递函数不仅可以用于瞬态，周期及随机温度变化，而且还可以用于模式识别，有广泛的应用背景．
In this paper,author deduces the transfer function of heat conduction in flat plae where there is no internal heat source and initial temperature is constant.The paper also discusses the singularity of the transfer function and presents several characteristic equations,impules response function and frequency response function under normal circumstances.The graph in this paper can be used to deduce the frequency response function of flat plate.The goal of this paper is to fully understand the characteristics of heat conduction in plate by deducing and discussing the transfer function of heat conduction in plate.The heat conduction transfer function of plate can not only be used in the transient,cyclic and random change in temperature,but can also be used in mode recognition.It has an extensive application background.
