摘要

目前的主流觀點認為非傅立葉熱傳現象是肇於熱擴散的時間延遲。然而時間延遲的熱擴散，違背了熱力學第一定律。因此本文展示藉由電熱類比法則及符合實驗觀察現象，支持以熱感解釋熱慣性的合理性。以時域響應設計熱慣性量測儀，包含實驗平台、微控制處理器、驅動電路、高頻寬的熱電偶、信號放大器、信號收集分析與繪圖，並量測數種非均質材料，與改變材料尺寸確立熱傳現象是以波動形式傳遞，並藉由實驗與熱感模型數值分析以求出熱感值

The current mainstream realizes that non-Fourier phenomena in heat transfer are arisen from the time-delay in heat diffusion, But time-delayed heat diffusion contradicts the first law of thermodynamics. This paper show that the realization of thermal inertia by thermal inductance is supported by the principle of electro-thermal analogy and compatible with experimental observations.
This paper designed to measure the thermal inertia instrument by time domain response. Contains experimental platform, micro-control processor drive circuits, high-bandwidth、thermocouple、signal、amplifier、signal collection、analysis and mapping. we measure several kinds of non- homogeneous；And changing the material dimensions established forms of heat transfer phenomena are fluctuations transfer. Last we used experiment and numerical analysis in order thermal model of the thermal inertia values.
