熱分析法是一個廣義的名詞,包括熱重量分析法、示差熱分析法、示差掃描熱量計、膨脹計、電熱分析法及熱機械分析法等,在化學及有關方面以前二種為重要,其應用範圍已日趨廣泛,本文將熱重量分析法及示差熱分析法之原理及應用作一簡單的介紹,使讀者們對於此二種方法有一初步的認識。
Thermal analysis is a broad term which includes thermograuimetric analysis, differential thermal analysis, differential scanning calorimetry, dilatometry, electrothermal analysis, the-rmomechanical analysis etc. The former two methods are more important in chemistry and related fields. Their applications increase rapidly in recent years. The present paper gives a brief account on the principles and applications of thermogravimetric analysis and differential thermal analysis, so as to supply readers an introductory knowledge about these two methods.
