本研究主要是建立一套影像處理應用於非均勻材料之熱傳導分析系統，先把非均勻材料樣品解剖利用電子顯微鏡(SEM)拍攝其縱向面，並搭配影像處理分析其縱向面之結構圖，再加以輸入至COMSOL模擬軟體中來模擬非均勻材料樣品的熱傳導分析，可以利用多種非均勻材料的個別熱傳導係數透過熱傳導模擬去計算非均勻材料的整體熱傳導係數，不用透過實際量測的方式即可知道非均勻材料的熱傳導係數與熱阻值，在非均勻材料研究上可以更直觀的了解熱的傳導，將會有更多更好的產品出現。
　　目前普遍對非均勻材料的研究方式都是透過不斷地改良與反覆的實際量測，想要知道改良的結果就必須量測，每種非均勻材料都是需要很長時間的研究，因此將影像處理應用於非均勻材料之熱傳導分析導入研究中能更直接與清楚的知道熱的傳遞路徑、熱傳導係數與熱阻值，如此一來可以大大的節省人力資源的損耗與實際量測所需之費用，提升產業的價值。

This study is to establish a set of image processing applied to the thermal conductivity of the composite material analysis system. The longitudinal surface of the composite sample was first analyzed by electron microscopy (SEM), and the longitudinal structure of the composites was analyzed by image processing. The heat transfer analysis of the composite samples was simulated by inputting into COMSOL simulation software. The overall thermal conductivity of the composites can be calculated by thermal conduction simulation using the individual thermal conductivity of multiple composites. The thermal conductivity and thermal resistance of the composites can be known without the actual measurement. In the composite material research can be more intuitive understanding of the heat conduction, there will be more and better products appear
At present, the common research methods of composite materials are through continuous improvement and repeated actual measurement. Want to know the results of the improvement must be measured. Each composite material takes a long time to study. Therefore, the image processing can be applied to the heat transfer analysis of composite materials into the study can be more directly and clearly know the heat transfer path, thermal conductivity and thermal resistance. So that can greatly reduce the loss of human resources and the actual measurement of the cost required to enhance the value of the industry
