摘　　要：本文根据现代控制论的状态空间原理,提出了一种计算多层壁传热反应系数的新方法。它通过计算系统的状态转移矩阵,不用求根而直接求得传热反应系数。该方法简易可行,用于工程计算具有足够的精度。In this paper, Based on the state space principle of modern con trol theory a new approach to calculating thermal response factors of multilayer walls has been proposed. Using this approach through calculation of the state transition matrix of a system, the thermal response factors can be directly obtained without need to find the roots. This method is feasible and easy to use with a sufficient accuracy for engineering applications.
