| 摘 要： | 本文给出一种首先利用Laplace变换求解在单位脉冲作用下多层壁表面的热流响应函数,然后利用求解导热反问题的解析公式求解出多层壁各层中的温度响应函数.对任意温度扰量作用在多层壁的边界条件下,利用了关于线性系统的DuhameI积分原理求解整个多层壁的温度场.两个计算实例说明了这种方法是极为有效的.

| Abstract: | In this paper, we use the Laplace transform method for solving the response functions of the transient heat flow through the exterior and interior sufaces of composite layers to a possitive unit excitation. At the same, we use the exact solution of inverse conduction for solving the functions of the transient temperatures in the composite layers with the response functions of the heat flow through the exterior and interior of the structure. Finally, for any boundary condition we invoke Duhamel's convolution therom of linar system for solving the transient temperature in the composite layers with the response functions of the transient temperature in the composite layers. Two examples show that the method is efficient. |
