It will present a new method - frequency - domain regression ( fdr ) method based on system identification theory for calculating transient heat flux through multi - layer walls. first, the frequency characteristics of the total transmission matrix are calculated within the frequency range concerned. then, a simple polynomial 5 - transfer function is yielded from the theoretical frequency characteristics for internal, cross and external heat conduction by applying appropriate identification algorithm, respectively
首先在所關心的頻域范圍內計算出總的傳遞矩陣的頻率響應,然後採用適應的辨識演算法從墻體不穩定傳熱的理論頻率響應中構造出一個簡單的多項式s -傳遞函數,該多項式s -傳遞函數與墻體瞬時傳熱的理論的超越s -傳遞函數完全等價。
