紅外線穩態熱阻量測法是一套具有高適應性及非接觸式的熱阻量測法，而在量測法中使用到的石墨粉雖能方便量測，但其卻也導致熱源覆蓋的部份溫度會有量不準的問題，因此本論文先藉由有限元素分析法探討石墨層帶來的影響，並根據熱阻的定義，在模擬中取出熱流傳遞方向物體之截面積變化，再以線性擬合的方式歸納出一個函數形式，用以推算物體表面最熱點溫度，最後進行實驗並與模擬結果做相互驗證。

Measurement of thermal resistance with infrared at steady state is a high adaptive and non-contact measuring method for thermal resistance. However, the graphite layer is convenient for measuring method, but it also brings out a problem that causes the temperature error on the heat source area. Therefore, in this research, finite element analysis (FEA) method is used to discuss temperature error from graphite layer. Accor-
ding to definition of thermal resistance, finding the effective cross-
sectional area along heat transfer propagation direction and using linear fitting to find a functional form which is used to calculate the highest temperature on the surface of sample. At last, performing experiment confirm simulation result.
